PURPOSE To evaluate the diagnostic usefulness of positron emission tomography (PET) with fluorine-18 fluorodeoxyglucose (FDG) in patients with primary colorectal carcinomas. MATERIALS AND METHODS Forty-eight patients with biopsy-proved (n = 44) or high clinical suspicion for (n = 4) colorectal cancer underwent whole-body PET after intravenous(More)

To see whether the fecal coproporphyrin III:coproporphyrin I (CIII:CI) ratio (determined by HPLC) would be suitable for screening patients at risk of hereditary coproporphyria (HC), we compared such ratios with the lymphocyte coproporphyrinogen oxidase (EC 1.3.3.3) activities (COOX) in 38 subjects from one large family and two smaller families with HC. The(More)
BACKGROUND Angiotensin-converting enzyme inhibitors have been shown to reduce the risk of end-stage renal disease and death in non-transplant patients with proteinuria. We examined whether ramipril would have a similar beneficial effect on important clinical outcomes in kidney transplant recipients with proteinuria. METHODS In this double-blind,(More)
The Performance and Responsibility Guidelines for the Nuclear Medicine Technologist were initially developed by the Socio Economic Affairs Committee and approved in 1994 and revised in 1998. Over this past year, the Academic Affairs and Socio Economic Affairs Committees have worked on revising the 1998 guidelines to bring them in line with current practice(More)
BACKGROUND In end-stage renal disease (ESRD) patients, increased arterial stiffness detected by carotid-femoral pulse wave velocity (cf-PWV) is associated with fatal cardiovascular events and all-cause mortality. Since cf-PWV is an operator-dependent technique, poor reproducibility may be a source of bias in the estimation of arterial stiffness. (More)
The major types of cancer studied at the authors' facility were colorectal (107 patients), head and neck (122 patients), gastric/esophageal (57 patients), lung (59 patients) and lymphoma (26 patients). This article presents guidelines and techniques for obtaining optimal PET studies. The authors devised these guidelines through trial and error and hope that(More)
BACKGROUND Documentation of the profiles of porphyrins in hepatobiliary disease is limited. Strong associations of hepatitis B and C virus infections with porphyria cutanea tarda have suggested causal relationships. This study aimed to determine the nature of porphyrin abnormalities in hepatobiliary disease and the effect of interferon-alpha on porphyrin(More)
