The purpose of these guidelines is to assist physicians in recommending, performing, interpreting, and reporting the results of 18 F-FDG PET/CT for oncologic imaging of adult and pediatric patients. PET is a tomographic scintigraphic technique in which a computer-generated image of local radioactive tracer distribution in tissues is produced through the(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)
The purpose of this Procedure Guideline is to assist physicians in recommending, performing, interpreting, and reporting the results of SPECT/CT for imaging of adult and pediatric patients. SPECT is a tomographic scintigraphic technique in which a computer-generated image of local radioactive tracer distribution in tissues is produced through the detection(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)
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)
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)
