Radiologic investigation of splenic trauma.

The radiologic findings in blunt and penetrating splenic injuries are discussed with emphasis on the angiographic demonstration of these injuries. The angiographic findings are correlated with the time interval between trauma and radiologic investigation.

[Computer tomography in acute pancreatitis (author's transl)].

The computer tomographic appearances of acute pancreatitis have been analysed 33 patients. It is usually a simple matter to distinguish between the acute, oedematous pancreatitis, which can be treated conservatively, and the suppurative pancreatitis with haemorrhagic and necrotising features, which require surgical exploration.

[Computer tomography following blunt abdominal trauma (author's transl)].

The computer tomographic appearances of lesions of parenchymatous organs following blunt abdominal trauma are described in 13 patients (five liver, four renal, two splenic and two pancreatic injuries). The value of abdominal computer tomography is discussed in relation to the interval between injury and time of abdominal examination and compared with the diagnostic value of abdominal angiography.

[Computer tomography and retroperitoneal fibrosis (Ormond's disease) (author's transl)].

Four patients with retroperitoneal fibrosis (Ormond's disease) were examined by computer tomography; the appearances are described and the differential diagnosis discussed. Computer tomography clearly defines the proliferative-inflammatory process and together with conventional radiology, angiography and lymphangiography it permits a presumptive diagnosis of retroperitoneal fibrosis. The non-invasive nature of computer tomography makes it the method of choice for follow-up of this disease.

[Abdominal computer tomography].

In computer tomography of the abdomen the amount of diagnostic information obtained depends on the organ system examined and correlates with the topographical anatomy. The information gained by this non-invasive method results from the demonstration of contour alteration and from inherent density differences. Although at this point in time, while the process of evaluation is still in progress, it is too early to formulate definitive guidelines on the indications for computer tomography of the abdomen, we suggest, on the basis of experience hitherto, that computer tomography of the adrenals and the pancreas is better than the previously known image-producing diagnostic methods. The overall diagnostic value of computer tomography of the liver and spleen, depending on the pathology in question, is apparently at least equal to sonography, nuclear medicine and angiography. Computer tomography of the gastrointestinal tract and the kidneys, when compared to other diagnostic radiographic and sonographic investigations, at present adds little information, and for this reason has limited application in these systems. In contrast to this is the highly instructive computer tomographic examination of the extrarenal retroperitoneal space.

The bedside determination of extravascular lung water: a non-invasive double indicator technique using 123I-antipyrine, 113mIn-transferrin and external counting.

Using the formulae of Fazio and coworkers, we calculated the extravascular lung water per unit of blood volume (ELW/V) and per unit of blood flow (ELW/F) after intravenous injection of 113In-transferrin as the blood label, and 123I-antipyrine as the diffusible, i.e. water label. Time-activity curves were recorded over the right anterior upper chest wall using a mobile detector. The curves were digitalized and fitted to a gamma-variate using a GAMMA-11 computer. Area over height calculations gave the mean transit times (t). Sixteen control subjects, without evidence of cardiac or pulmonary disease, and 10 patients, with clinical and radiological evidence of left heart failure, were examined. In the control group ELW/V was 0.37 plus or minus 0.17 and ELW/F 3.39 plus or minus 1.56 (mean plus or minus 1 SD). In the patients ELW/V was 0.71 plus or minus 0.26 and ELW/F 13.10 plus or minus 5.67. The difference between both ELW/V and ELW/F for the control group and the patient group is statistically significant. Our values for ELW/V both in patients and control subjects are very similar to those obtained by Fazio and coworkers using H2 15O. However, our values for ELW/F differed from those of Fazio; this could be partly due to dependence of this parameter on the cardiac output.

[The normal pancreas as seen on the computerised tomogram (author's transl)].

The normal appearances of the pancreas as seen on computerised tomograms (EMI) has been demonstrated in fifty normal patients and correlated with fifteen post mortem studies on patients with a normal pancreas. The problems of optimal demonstration of the pancreas on computerised tomograms and possible sources of error in the interpretation of transverse pancreas tomograms are discussed.

[The radiological diagnosis of choledochal cysts (author's transl)].

The radiological features of congenital choledochal cysts are discussed with reference to three cases seen by the authors. The diagnostic problems are mentioned, and use of scintigraphy and ultrasound tomography at an early stage is recommended in order to define more clearly the indications for invasive radiological methods.

[Radiological and sonographic investigation of pancreatic pseudocysts (author's transl)].

Based on a retrospective study of 14 patients with pancreatic pseudocysts, the ultrasonic evaluation of the pancreas is discussed and correlated to the conventional radiologic, endoscopic and angiographic examinations. The pancreatic sonography, as a non-invasive examination, is the method of choice for pancreatic screening and is recommended whenever a pancreatic pseudocyst is suspected.
