Multiple CT imaging in pressure sores.

In patients affected by pressure sores, bones can be reached easily by the infection. This suggested a new way for a more precise diagnostic evaluation, looking at the most recent technological knowledge, which can offer a better evaluation of single lesions for a better planning of surgical operations. The possibility of performing multiple imaging under a CT guide, as well as a simple technique for contrast permanence within the sore, led the authors to demonstrate the validity of modern CT scanning as a main diagnostic method.

[New imaging with computed tomography in dental implantology]. / Nuovo imaging con Tomografia Computerizzata nell'implantologia dentale.

The authors report on a new image processing technique, for the imaging of both mandible and maxilla, which is very useful for oral specialists, especially in pre- and postoperative protocols for dental implants. After performing very thin axial scans (1-2 mm) with overlapping and without gantry tilt, of the mandible and/or maxilla, the data are reconstructed with a Elscint DentaCT software. With this program, multiple panoramic alveolar views can be obtained in a very short time (about 5 minutes), with a focal plane which can be easily modified by the operator; these planes are parallel to the curved axis of maxilla or mandible. Furthermore, the operator can get multiple images absolutely cross-sectional to the curved axis of alveolar regions (radial sections) and can image the number of cross-sectional planes and the distance between them. In all studied patients (41 over the last 6 months, 66 images overall), DentaCT yielded an excellent representation not only of all anatomical structures but also of every single implant; this allowed a complete preoperative planning based on morphovolumetric, densitometric and spatial data, together with the correct evaluation of implant positioning and of osteointegration success.

[Congenital anomalies of the vena cava and renal veins: CT aspects]. / Anomalie congenite della vena cava e delle vene renali: aspetti TC.

Starting from a few cases of abnormalities of the vena cava and of the renal veins, the authors did analyze the congenital abnormalities affecting the above mentioned districts.

[Computed tomography guided percutaneous aspiration and drainage of thoracic and abdominal fluid collections (author's transl)]. / Aspiration et drainage percutanés des collections thoraciques et abdominales sous contrôle tomodensitométrique.

Computed tomography can be of value in guiding percutaneous aspiration and drainage of thoracic and abdominal fluid collections of various origins and localizations. Puncture-aspiration is of diagnostic importance when computed tomography findings are non-pathognomonic. Techniques employed for percutaneous drainage of infected fluid are described. Puncture-aspirations and percutaneous drainage of infected fluid are described. Puncture-aspirations and percutaneous drainage under computed tomography guidance are free from major complications, and represent a more valid therapeutic method than surgery, being simpler to perform and supplying identical results.

[Myelography with B 15000, a new nonionic water-soluble contrast medium. Technical aspects and preliminary clinical experiences (author's transl)]. / Mielografia con B 15000, un nuovo mezzo di contrasto idrosolubile non ionico. Aspetti tecnici e prime esperienze cliniche.

This is a report of myelography findings obtained in 50 patients with B 15000 (Iopamidol), a new non ionic water-soluble contrast medium. The procedure was easily carried out with a tilting table wired to a TV image amplifier. The dose of contrast medium injected intrathecally was 10 divided by 15 cm3 of a preconstituted solution containing iodine 200 or 300 mg/cm3. There were no accidents or major complications. The myelograms obtained with the test material afforded accurate diagnosis of intramedullary and extramedullary lesions, and signally of intervertebral disk protrusion and hernia.
