[Computerized tomography: physiological reheightering of the images by sugars (author's transl)].
During experimental utilization on the dog (per os) of several types of materials capable to be modified by the liver after digestive absorption, sugars appeared naturally opaques in the gastric cavity and so they could substitute in C.T. to the habitual materials of contrast, we also notice some belated modifications on intra hepatic density that might be in relation with the metabolism of intra hepatic glucose.
The use of iodolipids in hepatosplenic computed tomography.
Iodolipids have been used as a contrast medium for hepatosplenic computed tomography (CT) in 148 patients. In all but two of these cases, the contrast material was injected by the intravenous route. The method appears to be safe due to the marked reduction of dosage in CT compared with conventional radiographic iodolipid hepatography. This decreased dosage is made possible by the improved density and spatial resolution of CT. Pictorial and histographic densitometric analysis of normal and abnormal liver after iodolipid administration yields considerable diagnostic improvement.
[Hepatic and pancreatic tomometry. Radioanatomy and application to hepatic pathology].
More than 250 hepatic and pancreatic tomometries were carried out on a first generation tomometer. Anatomical and tomometric correspondances carried out on the cadaver led to precise radiological anatomy of the abdomen. Tomometry either alone or carried out after impregnation of the liver parenchyma with an emusion of lipiodol in low dosage permits one to demonstrate hepatic lesions of the order of one centimeter diameter whatever their localisation. Densitometry differentiates not only solid lesions from fluid lesions but permits in certain cases a diagnosis of the nature of the lesion.
[Reconstruction of the floor of the nasal cavity, hemipalate, bucal cheek and lower lip].
We describe the surgical technique used to reconstruct a defect created by resection of a tumor of the palate, malar mucosa, lower lip and adjacent gingival mucosa. We used a microvascular radial forearm flap. A strip across the flap is de-epithelialized and the flap is folded in half at that point. The sides are used for the oral and nasal linings, respectively. The thinness of this flap, its vascularization and the length of its pedicle make this design possible. Four months after the surgery the patient was free of disease and had achieved adequate phonation and swallowing.
