tc-99m pertechnetate scintigraphy is the modality of choice for diagnosis of meckel's diverticulum. interpretation of meckel's scan identifies a focal area of radiopharmaceutical uptake in the anterior abdomen similar to normal gastric mucosa. the activity must be of the same pattern and intensity as gastric uptake. we present a 13-year-old patient with gastrointestinal bleeding and a...

background outcome determination of head trauma is important for medical decision-making. to determine the consequences by using ct findings, the marshall and rotterdam criteria were introduced. few studies have been conducted to determine the diagnostic value of the rotterdam criteria. objective this study assesses the diagnostic value of the rotterdam criteria score with early outcome for tra...

introduction: to retrospectively analyze the outcome of patients who underwent meckel’s scan in a local centre in hong kong over the past fifteen years. diagnostic values in different referring indications were also reviewed. methods: all patients who referred for meckel’s scan in a local hospital in hong kong from 1/1/1996 to 31/12/2010 were identified. patients’ demographic data, presenting s...

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...

background : glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. this study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation. methods : the study was a cross-sectional study evaluating patients with unstable shoulder...

This paper presents a detailed architecture and instruction set of the SCAN cryptoprocessor. The SCAN cryptoprocessor is a modified SparcV8 processor architecture with a new instruction set to handle image compression, encryption, and information hiding based on the SCAN methodology. The modules for image compression, encryption, and information hiding are synthesized in reconfigurable logic an...

We propose a new design for testability technique, Parallel Serial Full Scan (PSFS), for reducing the test application time for full scan embedded cores. Test application time reduction is achieved by dividing the scan chain into multiple partitions and shifting in the same vector to each scan chain through a single scan in input. The experimental results for the ISCAS89 circuits showed that PS...
