Sonographic assessment of acute changes in plaque size and echogenicity and in intima-media thickness of carotid arteries after neck radiation therapy.

Background: Ultrasonic assessment of acute changes in carotid artery walls before and after neck radiation therapy (RT).

Methods: Fifty cancer patients scheduled for curative neck irradiation were included and underwent sonographic examination of carotid arteries, with assessment of intima-media thickness (IMT) and plaque size and echogenicity before and immediately after completion of RT.

Results: IMT was linearly correlated with age and before RT (r = 0.

Preoperative evaluation of renal anatomy and renal masses with helical CT, 3D-CT and 3D-CT angiography.

Purpose: The aim of this prospective study was to determine the efficacy of three-dimensional computed tomography (3D-CT) and three-dimensional computed tomographic angiography (3D-CTA) that were reconstructed by using the axial images of the multiphasic helical CT in the preoperative evaluation of renal masses and demonstration of renal anatomy.

Materials And Methods: Twenty patients that were suspected of having renal masses upon initial physical examination and ultrasonographic evaluation were examined through multiphasic helical CT. Two authors executed CT evaluations.

[Evaluation of rhinorrhea by computed tomography cisternography].

Purpose: We aimed to emphasize the indication for and importance of CT cisternography in the diagnosis of rhinorrhea patients by reviewing the literature with the support of unenhanced cranial CT findings.

Materials And Methods: Unenhanced cranial CT with axial sections and CT cisternography with coronal sections were performed in 14 patients who had spontaneous (n = 3) and posttraumatic (n = 11), intermittent or continuous CSF rhinorrhea. The slice thickness of infratentorial planes was 5 mm and supratentorial planes 10 mm.
