Kent and Sussex Radiology group offers a full range of state of the art Nuclear Medicine diagnostic investigations at the Tunbridge Wells Hospital with one of the latest GE SPECT CT scanners installed in 2011. This combined dual headed Gamma camera and 16 channel multi slice CT scanner provides superb image quality.

The Nuclear Medicine service is directed by Dr Brendon Conry and supported by Dr Charles Wetton. They are both experienced Radionuclide Radiologists and are able to combine the functional imaging of nuclear medicine with the anatomical information of CT, MR and ultrasound to provide the most clinically useful reports for patients.

Dr Conry is one of only three Radionuclide Radiologists in Kent able to report PET/CT examinations for the nationally procured PET/CT service.

The SPECT CT option allows greater certainty of diagnosis in the most challenging areas of imaging. Not only can the scanner image more quickly for patient comfort but also previously performed CT or MR images can be fused with current nuclear medicine data.

 

CLINICAL USES OF NUCLEAR MEDICINE SCANS
  • Lung. V/Q scanning. This investigation for pulmonary embolism is being increasingly used in patients with renal failure because of Iodinated contrast administration risks. In pregnant patients half dose perfusion studies are obtained to minimise breast cancer risks to susceptible breast tissue, rather than utilising CT pulmonary angiography (CTPA).

  • Cardiac. MUGA scans to assess toxicity of chemotherapy in cancer patients.

  • Renal. Scans to assess for differential renal function, renal scarring or renal tract obstruction. Direct and indirect radionuclide cystograms to assess for vesco ureteric reflux.

  • Thyroid.  In the assessment of over active thyroid disease, thyroiditis and autonomous nodules.

  • Oncology.  Assessment of bony metastases and sentinel node imaging in breast cancer.

  • Orthopaedics. Assessment of bony lesions and metastases, bone infection, avascular necrosis and post-arthroplasty pain in both hip and knee replacements.

  • Endocrine.  MIBI scanning for parathyroid adenoma, in patients with raised calcium levels.  This is always combined with ultrasound to direct a unilateral surgical approach when appropriate. Octreotide scanning in the assessment of neuroendocrine tumours. MIBG scanning in the assessment of phaeochromocytoma, paraganglioma and other neuroendocrine tumours.

  • GI Tract. HIDA scans to assess for cystic duct obstruction and biliary dyskinesia. Red blood cell scans in the assessment of acute and chronic GI blood loss. Meckel’s scans to confirm the presence of a Meckel’s diverticulum.
