OBJECTIVE The purpose of this paper is to introduce the nuclear medicine technologist to a new radiopharmaceutical, 99mTc-apcitide, for imaging acute venous thrombosis. After reading this paper, the technologist should be able to: (a) describe patient preparation for imaging with 99mTc-apcitide; (b) state the amount of 99mTc-apcitide that is administered to patients for imaging acute venous thr...

We appreciate the comments of Drs. Eid and Otsuki regarding the recent article by Jones and Whitaker (2009). In a day where at one of our own medical institutions cadaveric dissection is being supplanted with what was described to one of us by an administrative faculty as ‘‘more sophisticated’’ means of teaching anatomy (e.g. radiology), we still feel strongly about the continued use of the ken...

Three sisters with cassava poisoning are described. A review of the toxic properties of cassava is presented together with discussion on the methods of its preparation, its adverse effects on man, its detoxification in the body, and the treatment of its poisoning.

Previously, technetium-99m-stannous pyrophosphate (99mTc-PPi) has been used to localize and estimate the size of myocardial infarcts in animals after permanent coronary artery occlusion. This study tested the hypothesis that 99mTc-PPi accurately sizes myocardial infarctions produced by temporary coronary artery occlusion and reflow in dogs. Three groups of dogs were studied: group A underwent 3...

BACKGROUND The purpose of this study is to describe the preliminary findings of 99mTc-labeled ethylene dicysteine deoxyglucose (99mTc-EC-DG) performed four weeks after chemoradiotherapy in patients with locally advanced head and neck squamous cell carcinoma. METHODS Review of nine patients with locally advanced head and neck squamous cell carcinomas imaged with 99mTc-EC-DG single photon emiss...

UNLABELLED This article explores the accumulation of 99mTc-tetraphenyl porphyrin sulfonate (TPPS4) at inflammatory sites, especially osteomyelitis, and compares the results with 111In Cl3 and 111In-WBC in an animal model. METHODS Osteomyelitis was induced in 12 New Zealand white rabbits by injecting staphylococcus aureus in the left tibia. Three weeks later, radiographs confirmed the disease....

A tetradentate chelating agent constituting of an iminodiacetic acid group and a nitrogen atom of pyridine, N-(2-pyridylmethyl)iminodiacetic acid (PMIDA), was coordinated with 99mTc and evaluated as a renal functional agent. The complex of PMIDA with 99mTc was prepared by using a stannous chloride solution as a reducing agent. The chelating efficiency was analyzed by thin layer chromatography a...

The aim of the present study was to assess the predictive value of captopril scintigraphy with the new renal agent 99mTc-ethylenedicysteine (99mTc-EC) for post-interventional improvement in blood pressure. Twelve patients who had persistently high blood pressure with previous demonstration of various degrees of renal artery lesion on angiography were included into the study. Baseline and captop...
