ABSTRACTThe water soluble contrast agents GastrografinR(Sodium diatrizoate and meglumine diatrizoate, Schering, Berlin), Iopamiro 300 R (Iopamidol, Schering, Berlin), and Dionosil AqueousR(propyliodone BP, Glaxo, England) were instilled into the tracheobronchial tree of rats in doses of either 0.1 ml and 0.25 ml. Rats being used as controls, underwent sham operations with the instillation of air instead of contrast agent. In all, 85 rats were used. All rats that had not already died from the effects of contrast agent were sacrificed 30 minutes after instillation.The relative effects of the contrast agents were measured by comparing: 1. survival time; 2. radiographic effects of the contrast agents on the lungs and; 3. pathological changes as estimated by post mortem lung section andmicroscopy.The least toxic agent was the one with the lowest osmotic activity, namely Aqueous Dionosil.It is therefore recommended that Aqueous Dionosil be used in preference to Gastrografin or Iopamidol for studies of the oesophagus whenever there is a danger of aspiration of contrast agent into the tracheobronchial tree.

摘要:

ABSTRACTSixty eight impotent men underwent corpora cavernosography and corpora cavernosal pressure measurements during saline infusion. Nineteen of the men had internal pudendal arteriograms. Correlation between the cavernosograms and saline infusion induced pressure measurements was “good” in 56/66(84%), “approximate” in 5/66(8%) and there was no correlation in 5/66(8%). Two patients were excluded for technical reasons. The spread of results and the good correlation of the two tests speaks for the accuracy of the method. It was of value in diagnosis and will be of paramount importance if veno occlusive surgery becomes a reliable method of tr

摘要:

ABSTRACTCerebral venous malformations (CVM) are increasingly being recognised with the widespread use of CT scanning. Five cases are presented which demonstrate typical angiographic features and CT findings. These lesions when located in the cerebral hemispheres are benign and have been distinguished from the better known arteriovenous malformations on the basis of their characteristic angiographic features. CT findings have been considered nonspecific but our early post contrast CT scans demonstrate characteristic features suggesting that in many cases the diagnosis of cerebral venous malformations may be made on the CT scan alone.

摘要:

ABSTRACTFour newborn neonates with a historyof birth trauma and significant neurological signs were examined with both ultrasound and computed tomography (CT) performed within hours of each other. Ultrasound was inadequate in initial assessment, as it missed or underestimated posterior fossa haemorrhage, particularly where this was extraparenchymal or vermian. CT is the examination of choice in these patients.

摘要:

ABSTRACTThere is no place for investigative CT scans in patients who have the classical triad of abdominal aortic aneurysm rupture, namely excruciating abdominal pain or backache, a pulsatile mass and hypotension. These patients require immediate surgery. However, in the absence of this triad, CT scans play an important role in the diagnosis of abdominal aortic aneurysm rupture. The CT scan findings will dictate whether the patient requires immediate surgery as in the case of acute rupture, or, whether the surgery can be delayed up to 24 hours to allow for stabilisation and hydration, as in the case of subacute and chronic rupture.

摘要:

ABSTRACTA technique for performing direct coronal computed tomography (CT) of the pelvis on conventional CT equipment is described. Eighteen patients have been examined by this technique and its possible applications in the evaluation of patients with anorectal and genitourinary anomalies, pre and postoperatively, are discussed.

摘要:

ABSTRACTType I choledochal cysts were diagnosed on ultrasonography in 14 patients. The cysts were seen as oval or fusiform anechoic structures located in the subhepatic space and separate from the gallbladder. The continuity of the cyst with the bile duct in the porta hepatis was a specific feature for correct diagnosis of the condition.

摘要:

ABSTRACTA patient is presented who developed CNS lymphoma following a renal transplant. The lymphoma had the typical radiographic appearances of CNS lymphoma and responded to conventional radiotherapy. He is clinically well 12 months after completing radiotherapy. The question of whether these tumours are true lymphomas has yet to be answered and the optimal radiotherapy dose is not determined.ABSTRACTLymphoma is a well recognised complication of immunosuppression. A case is presented of a patient who developed CNS lymphoma thirty‐three months after renal transplantation. The incidence and characteristics of lymphoma developing post‐transplantation and the treatment of central nervous system (CNS) lymphomas are discus
