To investigate the relation between temporal artery biopsy (TAB) length and diagnostic sensitivity for giant cell arteritis.Histological TAB reports generated from four hospital pathology departments were reviewed demographics, histological findings, formalin fixed lengths. A was considered positive arteritis if there a mononuclear infiltrate predominating at media-intima junction or in media.Among 1821 reviewed, 287 (15.8%) excluded because of missing data, sampling errors, age < 50 years....

Summary Cystic echinococcosis (CE) caused by larval stage of Echinococcus granulosus, is an endemic zoonosis in Iran particularly rural regions. The objective this study was to determine the prevalence CE among communities Kerman using ultrasonography (US) and serology. Province, southeastern Iran, largest province, with 2.9 million inhabitants. A sample 1140 individuals (200 males 940 females) selected randomized cluster sampling 2006–2008. After acquiring informed consent for each...

In Brief Study Design. This study measured the frequency of lumbar intervertebral disc nucleus pulposus microscopic calcification and angiogenesis in adult patients undergoing discectomy compared to normal cadavers. Objective. The results were determine relationship between with degeneration type, histopathological angiogenesis, patients' age, gender, duration symptoms. Summary Background Data. True or degenerated discs have not been fully defined nor linked type angiogenesis. Some studies...

Purpose: Estimated dose rates that may result from exposure to patients who had been administered iodine‐131 ( 131 I) as part of medical therapy were calculated. These effective rate estimates compared with simplified assumptions under United States Nuclear Regulatory Commission Guide 8.39, which does not consider body tissue attenuation nor time‐dependent redistribution and excretion the I. Methods: Dose estimated for members public potentially exposed external irradiation recently treated...

The U.S. Nuclear Regulatory Commission (USNRC) initiated a contract with Oak Ridge National Laboratory (ORNL) to calculate radiation dose rates members of the public that may result from exposure patients recently administered iodine-131 (131I) as part medical therapy. main purpose was compare rate estimates based on point source and target values derived more realistic simulations human target. latter considered time-dependent distribution 131I in patient attenuation emitted photons by...

A new photon skin dosimetry model, described here, was developed as the basis for enhanced VARSKIN 4 thin tissue code. The model employs a point-kernel method that accounts charged particle build-up, attenuation and off-axis scatter. Early comparisons of against Monte Carlo transport simulations show is highly accurate very small sources on surface, although accuracy at shallow depths compromised radiation are clothing or otherwise elevated from surface. Comparison results provided...

An updated version of the skin dose computer code VARSKIN, namely VARSKIN 4, was examined to determine accuracy photon model in calculating rates with different combinations source geometry and radionuclides. The reference data for this validation were obtained by means Monte Carlo transport calculations using MCNP5. geometries tested included zero volume sources point disc, as well sphere cylinder. Three directly on skin, off an absorber material between only air gap skin. results these...

<title>Abstract</title> Purpose To determine the prevalence of different EICA variations in CT angiography (CTA) neck and its predisposing factors. Methods In this prospective study from 2021 to 2023 that was conducted radiology department Shafa Hospital, Kerman, Iran, all patients who had undergone CTA were invited participate study. Expert radiologists blindly examined each image for following: variations—coiling, kinking, straight morphology, tortuosity—and distance between internal...

Glomus tumors are rare and few cases reported in the literature. They typically occur females on digits of hands. We report a case 30 year-old woman who presented with mass that developed distal tip her right thumb after traumatic injury. Magnetic resonance imaging (MRI) was conducted resection performed. Histopathology confirmed glomus tumor. Clinical presentations non-specific, mainly consisting small chronic pain, lengthy time to diagnosis potentially improper management. MRI is preferred...

Magnetic Resonance Imaging (MRI) provides a non-invasive manner to aid clinical diagnosis, while its limitation is the slow scanning speed. Recently, due high costs of health care and taking account patient comfort, some methods such as Parallel MRI (pMRI) compressed sensing have been developed reduce MR duration under sampling process. It almost unavoidable accept doses X-rays in computed tomography (CT scans). If one could find more efficient way represent required visual information,...

Height, shape and anteroposterior diameter of normal pituitary gland in 15 to 40 years old population

Multiple sclerosis (MS) as a complex neurological abnormality is marked with loss of myelin and axons due to chronic inflammatory autoimmune responses. The modulatory properties the low dose radiation (LDR) on immune responses have well known.The current research aimed assess impacts LDR disability in patients suffering from MS.This experimental pilot study was done 10 secondary progressive multiple (SPMS). After magnetic resonance imaging, SPMS were treated by at daily 2 Gray for 5...
