The tomographic apparatus, technique of examination, and radiation exposure will be discussed. Examples of normal and pathologic anatomy of the cervical, thoracic, and lumbar spine will be presented. In the lumbar spine cross-sectional views of stenotic canals due to facetal hypertrophy, congenital stenosis, spondylolithesis, and ventral overgrowth of spine fusions will be demonstrated. Measurements of the sagittal and interpedicular distances on conventional x-rays have correlated poorly with the anatomic state in lumbar stenosis. A high degree of correlation has been demonstrated by plotting the cross-sectional area configuration of the bony canal, as well as a new measurement, the interfacet distance, on axial tomograms. Transverse axial tomography is an exciting, new approach in neuroradiology for the evaluation of spinal disorders which have primarily axial distortion.</p>","PeriodicalId":75747,"journal":{"name":"CRC critical reviews in clinical radiology and nuclear medicine","volume":"8 3","pages":"279-328"},"PeriodicalIF":0.0,"publicationDate":"1976-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11983548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Essential knowledge about pitfalls in tomography. 关于断层扫描陷阱的基本知识。

{"title":"Essential knowledge about pitfalls in tomography.","authors":"K R Kattan","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Tomographic cut is not synonymous to a roentgenogram of an anatomic cut. Blurring is inherent in the tomogram, and the edges do not appear as sharp as in the conventional roentgenogram. Part of the contrast is lost in tomography. Therefore, when tissue contrast is low, or when we intend to see an entire structure in one cut, zoneography is preferred. On the other hand, when many details are crowded in a small area and/or when the tissue contrast is high, a thin section tomography is indicated. Proper knowledge of the level of area of interest (focal plane) and proper spacing of the cuts decrease radiation and expenses. The Law of Tangent, namely, \"The edge of a structure should be momentarily parallel to the beam at the focal plane, in order to show on the film,\" is an essential part of every tomographic study. The Law of Tangent applies equally to spheres and other curved surfaces. The effective tomographic angle is the angle described by the tube during exposure. The thickness of the cut depends on the effective tomographic angle. Prior viewing of conventional roentgenogram and proper knowledge of the mechanism of parasitic and phantom images help us to avoid mistaking these images as real structures.</p>","PeriodicalId":75747,"journal":{"name":"CRC critical reviews in clinical radiology and nuclear medicine","volume":"8 3","pages":"329-67"},"PeriodicalIF":0.0,"publicationDate":"1976-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11983551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The clinical spectrum of antibiotic-related pseudomembranous colitis, ranging from a nonbloody, watery diarrheal state to a life-threatening condition mimicking an acute surgical abdomen, is reviewed. The classic proctoscopic and pathologic findings, as well as common problems encountered in interpretation, are discussed. A complete review of the spectrum of radiographic findings is presented from the nonspecific to the quite characteristic radiographic findings, including both plain film and contrast studies of the colon. These findings are contrasted with the X-ray features of other inflammatory and ischemic colitides and a differential diagnosis is discussed. A section dealing with the treatment of antibiotic-associated pseudomembranous colitis will be included. This section will review the various modes of therapy that have been employed.

The abnormal brain scan: specificity of descriptive parameters. 异常脑部扫描:描述性参数的特异性。

{"title":"The abnormal brain scan: specificity of descriptive parameters.","authors":"D D Patton","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>When a brain scan is abnormal, one can often describe the abnormality in terms of its location, shape, sharpness, brightness, and other descriptive parameters. Certain types of abnormality have been linked to certain specific diagnoses: for example, a crescent-shaped lesion would suggest subdural hematoma to many people, a wedge-shaped lesion would suggest cerebral vascular accident, etc. Some features thought to be characteristic of certain diseases are actually quite nonspecific. For example, the \"doughnut\" sign--at first believed to be characteristic of brain abscess--has also been found in primary and metastatic tumors, CVA, and subdural hematoma. The \"crescent\" sign that was at first thought to be specific for subdural hematoma occurs also in meningitis, scalp or skull trauma, meningioma en plaque, etc. Some features of abnormalities are highly specific for certain diseases; e.g., wedge- or flame-shaped lesions are rarely seen with disorders other than CVA, and lesions in the midline or in the posterior fossa are almost invariably tumors.
