A clinical and roentgenographic analysis of 13 patients with pathologically proved xanthogranulomatous pyelonephritis (X-P) has demonstrated that many previously accepted truisms associated with this disease may not be valid. As a result of this study it is suggested that X-P: 1. Does have a prominant female distribution. 2. May arise relatively acutely. 3.(More)
BACKGROUND The left-ventricular ejection fraction (EF) and end-systolic volume (ESV) are strong predictors of prognosis for cardiac death. Gated myocardial perfusion single-photon emission computed tomography (gSPECT) may be used to measure ESV and EF. However, systematic differences may exist between referred populations. Our aim was to derive male and(More)
Rash, lymphadenopaty, splenomegaly, periorbital edema, and hepatitis occurred in an 18-year-old woman who was taking phenobarbital and hydrochlorothiazide. Tests for fluorescent antinuclear antibody and hepatitis-associated antigen and antibody were negative. Liver biopsy was not characteristic of viral hepatitis. Clinical recovery occurred within two(More)
The purpose of this study was to compare six methods of measuring the left ventricular (LV) transient ischaemic dilation (TID) ratio during stress-rest myocardial perfusion single-photon emission tomography (SPET). The TID ratio was defined as the mean LV short-axis area at stress divided by the mean LV area of similar slices at rest. The centre of the LV(More)
The purpose of this study was to compare the performance of automatic detection of coronary artery disease (CAD) with that of expert observers. A male and female normal image template was constructed from normal stress technetium-99m single photon emission computed tomography (SPECT) studies. Mean and standard deviation images for each sex were created by(More)
BACKGROUND AND AIM Extra-cardiac activity can interfere with observer interpretation of myocardial perfusion single photon emission computed tomography (SPECT) images. Fatty meals and drinks to reduce interference have been tested; however, a simple study of delayed imaging with (99m)Tc-tetrofosmin and (99m)Tc-sestamibi has not been specifically addressed.(More)
BACKGROUND In the UK, guidewires have traditionally been used for localisation of non-palpable breast lesions in patients undergoing breast conservation surgery (BCS). Radioactive Seed Localisation (RSL) using Iodine-125 seeds is an alternative localisation method and involves inserting a titanium capsule, containing radioactive Iodine-125, into the breast(More)
