O-(2-18F-fluoroethyl)-L-tyrosine (18F-FET) PET as a potential selection tool for second surgery in glioblastoma patients.

Background: Treatment-related changes still represent a diagnostic challenge in the management of patients with suspect of recurrent glioblastoma. The specificity of conventional MRI in detecting recurrence remains limited. Brain PET imaging provides information on tumor metabolism and can contribute to improving the diagnostic accuracy of cerebral neoplasms.

111In platelet scintigraphy for the noninvasive detection of carotid plaque thrombosis.

Background And Purpose: Thrombosis on atherosclerotic lesions in the large extracranial arteries is the main cause of embolization in the distal cerebral circulation and thus is involved in the pathogenesis of ischemic stroke. The assessment of biological characteristics of lesions that are predictive of thrombotic complications might help in stratification of the risk for stroke but is currently imperfect.

Methods: We compared the performance of (111)In-platelet scintigraphy with blood pool subtraction, ultrasound-based tissue texture analyses, and transcranial Doppler techniques in their ability to predict the occurrence of superficial thrombosis or the presence of a lipid pool in carotid artery plaque specimens removed at the time of carotid endarterectomy in 22 patients with unilateral carotid artery stenosis of >70%.

Sentinel node biopsy in clinical stage 1 melanoma: rationale for restaging and follow-up.

Lymph node involvement appears to be the most significant prognostic factor in patients affected by melanoma and has been shown to reduce the five-year survival by 40%. We studied 31 patients (15 M; 16 F; age range, 28-83 years) with clinical stage 1 (CS1) intermediate thickness (0.75-4 mm) melanoma.

One laparoscopic puncture for treatment of ovarian cysts with adnexal torsion in early pregnancy. A report of two cases.

In two cases a simple laparoscopic technique was used to treat ovarian cysts with adnexal torsion in early pregnancy. A single laparoscopic route was sufficient. This procedure has great value for girls and young women for whom the preservation of fertility is a major concern.

[Hepato-cholescintigraphy using technetium Tc 99m diethyl IDA in the follow-up of biliodigestive anastomoses].

The results of a study conducted on 24 patients given biliodigestive shunts are reported. Follow-up involved cholescintigraphy using 99m-IDA technetium. This examination provided valuable information about the morphodynamics of biliary flow and when the biliary peak and intestinal appearance times were lengthened, it was also able to identify significant obstructions.
