Comparative Study[Computerized tomography in the study of thoracic-pulmonary complications after liver transplantation].
To review the role of Computed Tomography (CT) in thoracic complications following orthotopic liver transplantation (OLT). ⋯ Chest CT has relatively uncommon, and sometimes only clinical, indications in post-OLT patients. The technique is chosen based on clinical-radiographic findings. CT proved useful in showing negative cases and in detailing clinical and radiographic findings but must be integrated with clinical findings to define inflammatory and neoplastic conditions.

Comparative Study[Liver trauma due to penetrating lesions: miscellanea, personal case series, clinical and CT findings].
Penetrating liver wounds are related to many causes and rank second after blunt abdominal and liver trauma. We will report the clinical and radiological findings of our personal series of patients with penetrating trauma, especially by firearms and stab and cut wounds. We will also try to define the diagnostic workup of these traumas, which is especially based on CT signs of liver damage and associated changes and which is of basic importance for following treatment, both surgical or conservative. ⋯ Penetrating wounds to liver and abdomen are less frequent than those to the chest. In the past decade the use of CT has changed the diagnostic and therapeutic approach to such injuries completely, decreasing the resort to explorative laparotomy and hepatorrhaphy. Indeed, CT provides a clear picture of the extent and severity of damage, which permits to choose a conservative treatment in case of intraparenchymal hematomas and lacerocontusive foci without hemoperitoneum, which can be followed-up with physical and CT examinations. Moreover, Helical CT could provide the early diagnosis of active bleeding in the peritoneum and of focal bleeding in the liver, thus permitting prompt hepatorrhaphy or targeted hepatectomy. A diaphragm injury suspected at CT should always prompt the surgeon to intervention, especially when hemothorax, lung base pneumothorax, large liver hematoma or tear of the liver dome are associated. Finally, subdiaphragmatic free gas indicates gut perforation associated with liver damage, in which case surgery is necessary too.

Comparative Study[Diffusion weighted MR: principles and clinical use in selected brain diseases].
To define the principles and technical bases of diffusion weighted MR imaging of the brain and report our experience in the evaluation of selected brain disorders including age-related ischemic white matter changes (leukoaraiosis), neoplastic and infective cysts and wallerian degeneration. ⋯ Diffusion weighted MR imaging can be performed during a standard cranial MR examination and add useful clinical information in several brain disorders besides acute ischemic stroke.
