Leakage of the contrast medium was noted on angiograms of a patient whose autopsied brain disclosed typical pathological findings of hemorrhagic infarction. The case was a 63-year old woman with mitral valve failure, who suddenly had loss of consciousness and right-sided hemiplegia. The left carotid angiography performed six hours after onset demonstrated middle cerebral arterial axis occlusion...

M e t h o d s Design: Randomized placebo-controlled trial. Allocation: Unclear allocation concealment.* Blinding: Blinded (study investigators involved in the procedures).* Follow-up period: Up to hospital discharge. Setting: A coronary care unit in Centro Cardiologico Monzino, Milan, Italy. Patients: 354 patients (mean age 62 y, 81% men) who received primary angioplasty for ST-elevation myocar...

Since the first bronchography was performed by Chevalier Jackson’ in 1918 with the use of bismuth powder insufflated through a bronchoscope, there has been a constant search for more satisfactory bronchographic contrast media. The procedure did not gain widespread acceptance until the epoch making discovery by Sicard and Forestier2 in 1923, that Lipiodol made a satisfactory contrast medium for ...

Background: To evaluate gastrointestinal pathology in computed tomography (CT) scan, optimum distention, mural visualization and gastrointestinal tract discrimination are necessary. High attenuation oral contrast material in the form of iodine solution has drawbacks in mural visualization and tolerance. Milk can be used as a low attenuation CT oral contrast agent in gastrointestinal tract discr...

The purpose of this study was to identify the anatomic structures of the abdominal region of cat throughcomputed tomography (CT) to be used by veterinary radiologists, clinicians and surgeons. The abdominalregion of four cats were scanned twice, with and without using contrast medium in a same position, usinghigh-resolution imaging protocol. Slice intervals were 11 mm and were adjusted so that ...

This paper describes automatic sunspot recognition and classification from satellite images. Some experimental results on learning sunspot classification using data mining techniques are presented. The classification scheme attempted was the seven-class Modified Zurich scheme. Daily images of the solar disk were taken from the NASA SOHO satellite’s MDI instrument and sunspots extracted using im...

Flavonoids from Marchantia convoluta (MCF) were studied for their ability to inhibit the proliferation of 2.2.15 cells. All concentration of MCF inhibited the secretion of HBsAg and HBeAg in the cultured medium by 2.2.15 cells. Analysis of morphological changes of MCF-treated cells by phase-contrast microscopy revealed a possible mode of action for MCF: inhibition of proliferation of 2.2.15 cel...

introduction: myelograghy is a process of instilling contrast medium to the subarachnoid space for evaluating the spinal column by radiography. there are various contrast solutions for different radiographic studies but not all of them are suitable for spinal column evaluation. conclusions: our subject recovered completely without any sequelae after receiving appropriate treatment in a multidis...
