Diagnostic tests and scans

Our comprehensive diagnostic service covers all modalities including pathology, radiology and genetics, led by nationally recognised consultants and supported by dedicated on-site clinical teams.

Pathology tests


Within our network of state-of-the-art centres, we offer a comprehensive pathology service covering many different specialities, including breast, prostate and gynaecology. We use the latest proven screening and diagnostic techniques, conducted by experienced clinicians.

The pathology tests available at GenesisCare are listed below and you can read more on our patient site.

What we offer

Radiology tests


Our expert nuclear medicine physicians, radiographers and radiologists use the latest-generation technology to perform and interpret the scans. As well as established methods of scanning, we also use innovative solutions to identify disease and plan your treatments, such as PSMA PET/CT for prostate cancer and fMRI to examine the brain.

The radiology services available at GenesisCare are listed below and you can read more on our patient site.

What we offer

Genetic and genomic testing

Genetic and genomic testing

We’re pioneering the use of genomic profiling in the diagnostic pathway for all solid tumours, leukaemias, lymphomas or sarcomas.

We also offer BRCA-1 and BRCA-2 genetic testing for breast and ovarian screening.

MR imaging in neuro-oncology

Multi-modal MR imaging guides cognitive and neurological outcomes for patients with primary brain tumours and brain metastases.

Functional MRI

Functional MRI (fMRI) is a non-invasive imaging technique that is able to indirectly measure brain activity using fluctuations in brain energy demands related to neural signalling.1

We use fMRI to locate eloquent brain tissue related to speech, vision, movement, etc., as well as guide neurosurgical planning and tailor surgery for intrinsic brain tumours to avoid neurological deficit and improve patient outcomes. With the increasing neuro-oncological benefits of surgery for brain tumours, fMRI offers potential further applications to measure brain recovery processes to optimally stage and monitor treatments.2

Generally, fMRI shows high agreement with clinical gold standard tests, such as the amytal test and intraoperative direct brain stimulation, but importantly offers the advantage of being safe and non-invasive.

Diffusion tensor imaging

In addition, patients are offered a complementary MRI technique called diffusion tensor imaging (DTI). This imaging scan provides assessment of tissue microstructure and we use tractography to provide a 3D visualisation of neural tracts and the brain’s connectivity. This provides additional information about the location of important pathways for speech, movement, vision and other behaviours important for patient quality of life, whereas conventional MRI techniques provide only anatomical information.

These innovations that preserve quality of life are crucial to our approach to neuro-oncology which is to treat the whole patient, and not just the tumour. We are the first private service to offer this to our patients in the UK.

PET/CT scans

Our advanced imaging techniques and treatments help us to provide the best possible care and personalise your patient’s treatment to meet their exact needs. At GenesisCare, we aim to provide PET/CT scans within 48 hours of referral and send the results within 24-48 hours of completing the scan.

At GenesisCare, we offer a range of radioisotopes used with PET/CT scans at our Oxford and Windsor centres. 

The key types of PET/CT scans we offer are:

  • 68Gallium PSMA PET/CT
  • 18F PSMA PET/CT 
  • 18F FDG PET/CT 
  • 68Gallium Dotatate PET/CT

At GenesisCare, we aim to provide PET/CT scans within 48 hours of referral and send the results within 24-48 hours of completing the scan.


On-site radiopharmacy

At GenesisCare, we are proud to have our own onsite radiopharmacy at our Windsor centre. A significant obstacle when using PET/CT scans is obtaining the radiopharmaceuticals used in some of the scans. This is made especially difficult due to the short half-lives of some of the radiotracers. 

Having our own radiopharmacy eliminates this difficulty as we can produce our own 68Gallium PSMA and 68Gallium Dotatate labelled radioisotopes onsite.  This means we can provide our patients with fast access to the diagnostics scans essential to their treatment, without delay.

We provide fast access to our comprehensive cancer treatment pathways if needed, with treatment often starting within days of diagnosis.


Range of radiotracers and imaging techniques

Our range of advanced and innovative imaging techniques provide highly precise and detailed scans that help guide our diagnosis and treatment pathways, so we can achieve the best possible outcome for your patient. 


Outpatient oncology specialists

Our purpose-built centres at Oxford and Windsor have been awarded the Macmillan Quality Environment Mark (MQEM) and offer some of the UK’s most advanced cancer therapies. Our highly experienced multidisciplinary teams will care for your patient from their very first scan through to treatment and aftercare.

We offer a complete care plan that is designed to support your patient physically and emotionally, including exercise medicine and wellbeing therapies in partnership with Penny Brohn UK.

Types of PET/CT Scans

By using different radiotracers, we can diagnose and monitor a range of cancers.

68Gallium PSMA PET/CT scans are the gold standard imaging scan for prostate cancer. 68Gallium is combined with a unique carrier molecule to create the radiotracer. The carrier molecule is attracted to prostate-specific membrane antigen (PSMA). PSMA is a protein that is found on the surface of prostate cancer cells in high concentrations. This includes cancer cells that may have spread to other parts of the patient’s body. 68Gallium PSMA is an effective radiotracer used in diagnosing prostate cancer due to its increased specificity with low PSA (prostate-specific antigen) levels and sensitivity to tumour, lymph and bone metastases. 

A 68Gallium PSMA PET/CT scan is also superior to traditional bone imaging and can distinguish between bone damage caused by cancer and other non-cancer causes. We can closely and accurately monitor how well prostate radiotherapy or hormone therapy cancer treatment is progressing for a patient. 


Theranostics – 177Lutetium PSMA therapy 

We use 68Gallium PSMA PET/CT scans as the first step in our ‘seek and destroy’ Theranostics treatment for metastatic castration-resistant prostate cancer. The 68Gallium PSMA scan will show us if your patient is suitable for therapy using 177Lutetium PSMA and will be used to assess how well it’s working.  If suitable, we will use the radioactive substance 177Lutetium combined with PSMA to target the prostate cancer cells. Its unique ability to seek out the exact location of your patient’s cancer and any areas it may have spread to, means that treatment can be focused directly on these areas.

We also use 18F PSMA PET/CT at our Bristol centre through a fortnightly mobile unit. This works the same way that 68Gallium PSMA PET/CT scans do, but the radiotracer used is 18Fluorine. This radiotracer is easy to transport, which means we can offer these scans to more patients at a mobile unit.

You can refer for 68Gallium Dotatate PET/CT scans which are used to diagnose and assess primary and metastatic well-differentiated neuroendocrine tumours (NET) particularly in symptomatic patients with negative anatomical findings.  As NET tumours overexpress somatostatin receptors, Dotatate, which is an analogue of somatostatin, is a carrier molecule for the 68Gallium and provides a highly sensitive method for identifying NETs throughout the body. This scan also plays a key role in identifying if a patient may benefit from a Theranostics pathway by highlighting disease areas and suitability for 177Lutetium Octreotate treatment.

18F FDG PET/CT scans are also available at our Windsor and Oxford centres and are used to detect and access the metabolic activity of certain tumours including lung cancer, colorectal cancer, lymphoma, melanoma, breast cancer, ovarian cancer, brain cancer and multiple myeloma. FDG (fluorodeoxyglucose) is similar to naturally occurring glucose which all the cells of the body use for energy. As cancerous cells use more glucose than normal cells, this enables the 18F FDG PET/CT scan to demonstrate areas of increased uptake, making it an ideal imaging tool at diagnosis and for follow-up of treatment.

⁶⁸Gallium PSMA

The diagnostic gold standard for our prostate Theranostic service

Currently, all patients undergoing 177Lutetium PSMA therapy at GenesisCare are required to have a ⁶⁸Gallium PSMA PET/ CT scan.

PET/CT is a powerful modality used to detect metastases, stage cancers and, in the case of Theranostics, prepare for peptide receptor radionuclide therapy such as 177Lutetium PSMA therapy.

In recent years, various radio-labelled PSMA ligands have been investigated for PET. ⁶⁸Gallium PSMA is an effective radiotracer for use in diagnosis of prostate cancer, due to its increased specificity with low PSA levels and sensitivity to tumour, lymph and bone metastases. This is when compared to other radiotracers such as 11C Choline and 18F-fluoromethylcholine. PET with ⁶⁸Gallium PSMA is also superior to traditional bone imaging and can differentiate between bone damage caused by cancer and other causes, such as osteoporosis.2,3

Transperineal Vector prostate biopsy

Transperineal Vector prostate biopsy is a novel and innovative technique for prostate cancer assessment. We are the first healthcare provider in the UK to offer this procedure which is available at our centres in Cambridge and Windsor at our UrologyHub clinics.

The quality of well-established MRI US fusion transperineal template prostate biopsies under general anaesthesia is based on the high accuracy of the software, a fixed stepper mounted probe permitting minimal distortion of the prostate and visual tracking of needle by the template grid in-line with the US plain.

More recently introduced local anaesthetic TP biopsies use minimal numbers of entry points but require a mobile probe to allow inline needle tracking, which leads to distortion of the prostate, making visual or fusion targeting more difficult, as well as causing more discomfort for the patient.

VTRAX electromagnetic needle tracking, which provides needle trajectory tracking without direct view, allows the delivery of the benefits of the classic fusion TP biopsy technology, yet, through only two locally anaesthetised entry points whilst the probe and fusion can remain stable.

Evidence base of transperineal Vector prostate biopsy

We have evaluated TP Vector prostate biopsy since its introduction using patient reported outcome measures (PROMS) and oncological outcomes.

The procedure is extremely well tolerated. So far, no episode of retention has been reported and only one patient requested antibiotics for a minor urine infection.

Detection rates of targets are 95% with the highest ISUP grading or core length in the targets.

The new vector biopsies appear to deliver the high accuracy of established transperineal fusion technology with indication of improvement in tolerability and side-effects.


Patients with an indication for TP biopsy based on PSA, rectal examination and MRI are offered vector prostate biopsy.

  • Stepper-mounted ultrasound probe is placed in the rectum and local anaesthetic injected into the perineum
  • The US image set is fused with the MRI
  • A needle sheath with a VTRAX sensor is inserted into the perineum
  • The trajectory of the needle is tracked in an electromagnetic field – a circle shows when the needle trajectory cuts the sagittal US plane, which can then be directed onto the lesion of interest for biopsy
  • Targeted and systematic biopsies are taken
