introduction: gastric drainage disorder is one of the complications of gastric pull-up and esophagectomy after surgery which might lead to esophageal cancer and benign strictures. the aim of this study was to determine the role of pyloromyotomy on gastric drainage. materials and methods: in this prospective randomized controlled clinical trial study, we studied 51 patients in two matched groups...

A perennial difficulty in the field of radioisotope scanning* is the fact that the requirements for resolu tion and number of counts are specified independ ently although everyone knows that both contribute to the ultimate picture quality. This difficulty results from the fact that the image degradation due to blurring and that due to statistics are not directly comparable. Blurring introduces ...

Verified intracranial deposits of Hodgkin's disease are rare. Thus there was only one among 125 cases reported by John and Nabarro (1955). In the monograph by Williams, Diamond, Craver, and Parsons (1959) there were four among 1,992 cases. Todd (1967) reported two among 1,339 cases. The deposits are usually subdural, intracerebral metastases being exceptional. This rarity contrasts with the inc...

Evaluation of thyroid nodules remains a challenge for primary care physicians. To include or exclude the presence of malignancy in a thyroid nodule, radioisotope scan, ultrasound, and fine-needle aspiration biopsy of the thyroid generally are used. The objectives of this study were to determine the utility and cost effectiveness of fine-needle aspiration biopsy of solitary thyroid nodules in a ...

INTRODUCTION L,L-ethylenedicysteine (EC) is a new carrier of technetium Tc 99m (99mTc) with a lower affinity to plasma albumin in comparison with diethylenetriamine pentaacetic acid (DTPA). We compared 99mTc-EC scan with 99mTc-DTPA scan in diuretic renography for patients with obstructive uropathy. MATERIALS AND METHODS Thirty-three patients with upper urinary tract obstruction were randomly ...

BACKGROUND: Radioisotope bone scanning is frequently used to stage patients with suspected or proven malignancies. Since false-positive results are common, especially in the ribs, open biopsy is often necessary. The conventional approach of visual inspection of the bone scan image to guide the surgeon usually requires excision of a large area of one or two ribs to assure that the biopsy was per...

An information-theoretic pattern recognition method was used to construct descriptive models of data related to 1,674 radioisotope lung scan referrals for the purpose of assessing lung scan influence on diagnosis and management of pulmonary embolism. It was observed that, relative to other clinical information available prior to the scan, the lung scan significantly improved the ability of the ...
