[en] The book takes stock of the valid findings of computerized tomography. To begin with the technique, the image structure, and radiation protection measures are explained. Finally, serial CT and the use of CT in irradiation planning are briefly discussed. (MG)

[en] The book is intended as a source of reference and a guide to the full scope of diagnostic radiology and further imaging methods available to all those concerned with the medical care of bone and joint lesions, presenting in-depth information on the most significant and typical lesions, indication for and applications of the current surgical measures and the relevant implants, and giving answers to the specific problems encountered in the accident surgery department.

[en] The enormous technical development in the field of CT certainly has not yet come to an end, but it seems to have reached a point of saturation, so to speak. This impression gave rise to the wish to make an inventory of achievements and verified results. The various chapters of this book deal with the differential diagnosis and the interpretation of results to be achieved using computed tomography in case of various organic diseases. The inventory is rounded off by chapters devoted to technical aspects, radiation exposure and irradiation planning. From the great number of contributions discussing CT, primarily review articles and surveys have been selected for this book. (orig./MG)

[en] Three times the inferior mesenteric artery was embolized in one patient with recurrent gastrointestinal hemorrhage due to hypernephroma invading the left colon (tumorrecurrency after nephrectomy and radiation-therapy). The patient was inoperable. The bleeding could be stopped repetedly for several weeks. Fibrospum particles were used with the aim to obtain incomplete ischemia. So the danger to produce local necrosis was thought to be limited. (orig.)

[en] The arc of Buehler between the celiac and superior mesenteric arteries has to be considered as an embryological persistence of the portion of the ventral longitudinal anastomosis. The collateral development of the anastomosis refers to a different hemodynamic in the upper visceral arteries. We discovered the arc of Buehler in 14 cases among 340 selective celiac and superior mesenteric arteriographic studies. Its existence permits conclusions about further angiographic procedures and facilitates the interpretation of visceral collaterals. (orig.)

[en] Magnetic resonance tomography reliably provides all anatomic information necessary for the differential diagnosis of a urethral diverticulum even when other imaging procedures cannot provide conclusive evidence. In general, the methodological limitations concern only the less important detail findings such as representation of the neck of the diverticulum or the distinction between septated and multiple diverticula. In addition, possible complications and the pelvic anatomy are shown in one examination. Thus, magnetic resonance tomography has a key position among the imaging processes and should be used as the imaging procedure of choice for diagnostically doubtful cases. (orig.)

[en] Serial computed tomography following intravenous bolus injection of contrast agent is an important development in computed tomographic diagnosis. The technical necessities and methods of examination are discussed. Our experience with 108 examinations is evaluated. The additional information in terms of morphology and function is described. (orig.)

[en] Follow-up studies of 127 patients with local tumor regrowth after rectal amputation and continence-preserving resection for rectosigmoid cancer are reviewed. The sensitivity of various imaging techniques is discussed. For a rational follow-up program the conclusions below can be drawn: 1. Local tumor regrowth after resection is mostly extraluminal and may therefore be missed in its early stages by endoscopy. If endoscopic images are suspect and/or serum CEA titers are elevated, CT should be used as an additional tool. With it the diagnosis can be made earlier, the size of the pericolonic mass can be assessed and its resectability can be evaluated. 2. Local tumor regrowth following rectal amputation may be detected by closely spaced clinical examinations and serum CEA assays. The earliest objective evidence is obtained by CT. Postoperative base-line images improve conditions for a subsequent diagnostic work-up. Routine CT follow-ups should be reserved for high-risk cases. Curative treatment is currently the exception to the general rule. Radiotherapy is the most common palliative modality. 3. The role of MR in diagnosing tumor regrowth can currently not be established because comparative evaluations are not yet available. As far as can be said on the basis of available experience, MR has not brought any major advances for the early detection of tumor masses and the differentiation of scar tissues and tumor regrowths.
