We describe a new technique, known as coregistration imaging, which superimposes 99mTc isotope bone scans on to plain radiographs. We used the technique selectively in cases in which the nuclear medicine physician, who reported the isotope scan, had difficulty in localising the anatomical site of the abnormality. In the forefoot, coregistration of isotope scans did not help to localise patholog...

Lymphoedema (LOE) is an under-diagnosed condition which can cause severe incapacitating swelling of the extremities. Misdiagnosis and/or delayed diagnosis are common and the goal of further evaluation is to confirm the cause and determine the type and site of lymphatic obstruction. Lymphoscintigraphy (LSG) is a minimally invasive way of evaluation of the lymphatic system and can be used in the ...

OBJECTIVE To develop a list of 5 tests or treatments used in rheumatology that have evidence indicating that they may be unnecessary and thus should be reevaluated by rheumatology healthcare providers and patients. METHODS Using the Delphi method, a committee of 16 rheumatologists from across Canada and an allied health professional generated a list of tests, procedures, or treatments in rheu...

The ever-growing need for radiopharmaceuticals, i.e., compounds containing pharmaceutical drugs and radioisotopes used medical diagnostic imaging (SPECT/PET scan) treating neoplasms, is significantly leading to an increased demand such substances in hospitals clinics worldwide. Currently, most large-scale productions of required radiopharmaceuticals are carried out research reactors, via the fi...

introduction: radioisotope scanning is the best method for objective assessment of salivary gland function. thus, it was used in a randomized trial of concomitant pilocarpine for assessment of radiation-induced xerostomia, in addition to subjective evaluation by an approved questionnaire and objective standard xerostomia grading. methods: patients randomized in placebo-controlled trial of piloc...

A 63-year-old lady underwent right-sided nephrectomy for renal cell carcinoma (RCC) in 1991. She required a further nephrectomy in 2003 for RCC in the contralateral side rendering her haemodialysis dependent. Following 2-year disease free survival she was considered for transplantation. An initial CT scan of the abdomen in 2005 raised the possibility of bone metastases, promoting further invest...

Although it is recognized that hepatobiliary scan is of value in assessing postoperative complications of biliary surgery or cadaveric whole liver transplantation, there have been few reports regarding its usefulness following living donor liver transplantation. We performed living donor liver transplantation in a patient with biliary cirrhosis due to hepatolithiasis, using a right lobe graft f...

BACKGROUND The reported case illustrates an instance of colonic adenocarcinoma presenting as an isolated tumour 3 1/2 years after open surgery. The presentation was in some respects unique as it was complicated by an incisional hernia and occurred in the anterior abdominal wall. A literature review was performed. CASE PRESENTATION An 83 year old lady initially underwent an extended right open...
