Prognostic role of diffusion weighted and dynamic contrast-enhanced MRI in loco-regionally advanced head and neck cancer treated with concomitant chemoradiotherapy

, Germany) with a neck array coil. The diagnostic imaging protocol included axial T2-weighted sequences with short tau inversion recovery (STIR) from the base of the scull to aortic arch (TR/TE 5010/71 ms, TI 170 ms, flip angle (FA) 70°, receiver bandwidth 287 Hz/pixel, matrix size 256 x 256, slice thickness 3 mm, gap 0.3 mm and field of view (FOV) 18 x 18 cm). Axial slices that covered the entire primary tumour were selected for DWI and DCE-MR imaging. DWI images were acquired in axial plane using pulsed spin-echo echo-planar image sequence (TR/TE 3600/86 ms, receiver

CT features of normal lung change in asymptomatic elderly patients

, United Kingdom) with scanning parameters as follows; 0.75 mm collimation, slice thickness 1 mm, 100 kVp, 134 mA, and 0.625 mm collimation, slice thickness of 1 mm, 120 kVp, 165 mA, respectively. Images were acquired with 8 sequential axial slices; 4 slices on full inspiratory phase and other 4 slices on full expiratory phase to assess the degree of air trapping. The slices were performed at 4 levels: at the top of the aortic arch, at the carina, at the right inferior pulmonary vein, and at 2 cm above the right hemidiaphragm. Before scanning, participants were provided

Endovascular treatment of unruptured aneurysms of cavernous and ophthalmic segment of internal carotid artery with flow diverter device Pipeline

institution we have a single-plain C-arm system Axiom Artis (Siemens, Germany). We use a classical approach using the Seldinger technique. After the puncture of the femoral artery we introduce the angiographic catheter fist into the femoral artery and then via the aorta and the aortic arch into the common carotid artery. A detailed angiographic processing of the aneurysms with preoperative angiography in typical projections, rotating three-dimensional subtraction angiography with computerized data processing, construction and reconstruction of an aneurysm in the head

Aortic aneurysm

aging of the population, the rise in the number of smokers, the introduction of screening programs, and improved diagnostic tools. The disorder is more common in men than in women, with prevalence rates estimated at 1.3–8.9% in men and 1.0–2.2% in women. [ 1 ] However, thoracic aortic aneurysms (TAAs) have an estimated incidence of at least 5-10 per 100,000 person-years. [ 2 ] According to location, TAAs are classified into aortic root or ascending aortic aneurysms, which are most common (≈60%), followed by aneurysms of the descending aorta (≈35%) and aortic arch
