PURPOSE To compare lesion enhancement after injection of gadopentetate dimeglumine on spin-echo and gradient-echo T1-weighted images. METHODS A total of 48 contrast-enhancing intracranial lesions were evaluated using a spin-echo and two gradient-echo T1-weighted pulse sequences. Percent contrast, contrast-to-noise, and signal-to-noise measurements were made on the spin-echo T1-weighted, three...

A 26-year-old previously healthy man presented with a 1-month history of progressive mouth sores, eye discomfort, and skin rash. Over the 2 weeks before presentation, he had lost more than 10 kg (22 lb) because of difficulty in swallowing fluids and food, caused by the mouth sores. He had a history of herpes gladiatorum affecting his right shoulder. On physical examination, approximately 90% of...

We report a case of a retained graphite anterior chamber foreign body that was masquerading as stromal keratitis. A 28-year-old male visited with complaints of visual disturbance and hyperemia in his right eye for four weeks. On initial examination, he presented with a stromal edema involving the inferior half of the cornea, epithelial microcysts, and moderate chamber inflammation. Suspecting h...

tently seen in the patients in which the hyperemias were accessible for reliable rCBF investigations, we found it justified to discuss therapeutical possibilities. Our assumption of hyperemic borderzone as threatened areas with a potential to survive is derived from our own findings of impaired autoregulation, false autoregulation, and impaired C02-response in some of the hyperemic areas invest...

argas reflexus is considered obligate blood feeder that may cause skin redness and local swelling. for histopathological evaluation of biting site, pigeons were used as natural host species in this study. adult ticks were collected from urmia, north-west of iran and kept in a desiccator before their use in the experiment. sixteen pigeons were infested experimentally and were divided into 4 grou...

Hypersensitivity to ribitol teichoic acid (RTA), the major antigenic determinant of Staphylococcus aureus, may be important in a rabbit model of corneal phlyctenules and catarrhal infiltrates. Over a 5-month period, an enzyme-linked immunosorbent assay was used to measure immunoglobulin (Ig) G and IgA antibody levels to RTA in sera, tears, and corneas from rabbits immunized using the following ...

Abstract Background Primary breast edema can cause marked increase in skin thickness, density and echogenicity due to dense tissue filled with fluid so causes subsequent significant attenuation of both the x-ray ultrasound beams. The study aim is assess value contrast-enhanced digital mammography (CEDM) assessment characterization obscured underlying lesions cases primary edema. Results Fifty f...

PURPOSE To define the percentage of magnetization transfer of multiple sclerosis (MS) plaques, ischemic white matter lesions, and vasogenic edema to determine whether this measurement can help differentiate these entities. METHODS Findings were compared in 25 patients with proved MS, 20 patients with white matter ischemic lesions, and 72 patients with white matter edema (caused by tumors, inf...
