Contrast Ct

The incidence and prevalence of urinary tract calculi has increased significantly during the past decade. Accurate fast diagnostic modalities were developed to cope with such an increased trend. To date, non-contrast CT scan remains the diagnostic modality of choice for evaluation of patients with urinary tract calculi. However, contrast CT scans are gaining more interest. In this review, both diagnostic modalities were reviewed with the advantages and disadvantages of each. Non-contrast CT scan is a rapid, accurate, less hazardous, less expensive imaging modality that has a high sensitivity in detection of urinary calculi as small as 3 mm. However, it cannot evaluate other probable causes of flank pain. Thus, contrast CT scans can be used in situations where clinical presentation is suspicious and the possibility of other differential diagnoses is considered. Contrast CT scans do not decrease the sensitivity of detecting urinary calculi, and they do have a higher sensitivity in detecting small grades of obstruction as well as evaluating other possible causes of flank pain such as neoplasms, infectious, or inflammatory aetiologies.

Object. Many neurosurgeons routinely obtain computerized tomography (CT) scans to rule out hemorrhage in patients after stereotactic procedures. In the present prospective study, the authors investigated the rate of silent hemorrhage and delayed deterioration after stereotactic biopsy sampling and the role of postbiopsy CT scanning. Methods. A subset of patients (the last 102 of approximately 800 patients) who underwent stereotactic brain biopsies at the Toronto Hospital prospectively underwent routine postoperative CT scanning within hours of the biopsy procedure. Their medical charts and CT scans were then reviewed. A postoperative CT scan was obtained in 102 patients (aged 17–87 years) who underwent stereotactic biopsy between June 1994 and September 1996. Sixty-one patients (59.8%) exhibited hemorrhages, mostly intracerebral (54.9%), on the immediate postoperative scan. Only six of these patients were clinically suspected to have suffered a hemorrhage based on immediate postoperative neurological deficit; in the remaining 55 (53.9%) of 102 patients, the hemorrhage was clinically silent and unsuspected. Among the clinically silent intracerebral hemorrhages, 22 measured less than 5 mm, 20 between 5 and 10 mm, five between 10 and 30 mm, and four between 30 and 40 mm. Of the 55 patients with clinically silent hemorrhages, only three demonstrated a delayed neurological deficit (one case of seizure and two cases of progressive loss of consciousness) and these all occurred within the first 2 postoperative days. Of the neurologically well patients in whom no hemorrhage was demonstrated on initial postoperative CT scan, none experienced delayed deterioration. Conclusions. Clinically silent hemorrhage after stereotactic biopsy is very common. However, the authors did not find that knowledge of its existence ultimately affected individual patient management or outcome. The authors, therefore, suggest that the most important role of postoperative CT scanning is to screen for those neurologically well patients with no hemorrhage. These patients could safely be discharged on the same day they underwent biopsy.

Radiographic documentation of the rapid development of an aortic infection has not previously been reported. We report the case of a 68-year-old woman who presented with back pain. A computed tomographic(CT) scan documented a nondisplaced L1 compression fracture as well as an atherosclerotic but nonaneurysmal aorta. Two weeks after discharge, she developed left lower lobe pneumonia and was readmitted. A second CT scan was obtained because of continuous complaints of back pain. A contained rupture of the visceral aorta was now clearly visible. Emergent operation successfully repaired her aorta. The microorganisms responsible for aortic infection have changed since the widespread use of antibiotics. Patterns of aortic involvement have also evolved. The difficulty in making these diagnoses, the role of current antibiotic therapy, and the surgical options for these infections will be discussed.

Mummy 527 B* belongs to the “Giovanni Marro” Egyptian Collection of the Museum of Anthropology and Ethnography of the University of Turin. This mummy of a oneyear- old pre-dynastic child was found in Gebelein in 1935 in a small necropolis discovered during excavations of the “Missione Archeologica Italiana” led by G. Farina, the new Director of the Egyptian Museum of Turin, with the participation of Prof. G. Marro as anthropologist. A whole body spiral CT scan with thin slices (1,00 mm thickness, 0,5 mm reconstruction interval) was followed by multiplanar and 3D reconstruction. The aim was to evaluate the child’s age at death and the presence of lethal pathologies. This study confirms the fundamental role of non-invasive techniques in the study of such rare pre-dynastic specimens.
