Acute imaging does not improve ASTRAL score's accuracy despite having a prognostic value
(2014)Background The ASTRAL score was recently shown to reliably predict three-month functional outcome in patients with acute ischemic stroke. Aim The study aims to investigate whether information from multimodal imaging increases ... -
Anatomy and Complications Following Laparoscopic Sleeve Gastrectomy: Radiological Evaluation and Imaging Pitfalls
(2011)To evaluate the post-operative gastric anatomy depicted by upper gastrointestinal gastrografin swallow studies (UGI) and report radiological work-up and management of complications following laparoscopic sleeve gastrectomy ... -
Brucella spondylitis complicated by an infected abdominal aortic aneurysm and deep venous thrombosis: case report and review of the literature
(2008)Brucellosis is a common zoonosis, which still remains as a major health problem in certain parts of the world. Spondylodiscitis is the most frequent osteoarticular complication of brucellosis. Herein is reported an uncommon ... -
Celiomesenteric trunk demonstrated by multi-detector computed tomography angiography: two cases of a rare vascular variation
(2013)We present two cases of patients with celiomesenteric trunk in whom the celiac trunk and the superior mesenteric artery arise off a common vessel from the ventral part of the aorta, which was demonstrated by multi-detector ... -
Chordomas of the upper cervical spine: radiographic evaluation. Study of two cases and review of the literature
(2008)Chordomas are rare bony tumors, usually involving the skull base and sacrococcygeal spine, while least presented in cervical and thoracic spine. Chordomas of the cervical spine may cause variable neurological symptoms. ... -
Comparison of MR-arthrography and MDCT-arthrography for detection of labral and articular cartilage hip pathology
(2011)Objective To compare the diagnostic ability of MR arthrography (MRa) and MDCT arthrography (CTa) in depicting surgically proven hip labral tears and articular cartilage degradation. Materials and methods Labral pathology ... -
Dimensions of the lumbar spinal canal: variations and correlations with somatometric parameters using CT
(1998)The aim of this study was to investigate the correlation of vertebral dimensions with somatometric parameters in patients without clinical symptoms and radiological signs of central lumbar spinal stenosis. One hundred ... -
FDG-PET for detecting local tumor recurrence of ablated liver metastases: a diagnostic meta-analysis
(2012)Context: Scanty reports have focused on FDG-PET after radiofrequency ablation (RFA), for recurrence of hepatic metastases. Objective: To assess FDG-PET diagnostic accuracy on detection of recurrent hepatic lesions. Methods: ... -
Prognostic impact of tumor volumetry in patients with locally advanced head-and-neck carcinoma (non-nasopharyngeal) treated by radiotherapy alone or combined radiochemotherapy in a randomized trial
(2004)Purpose: Tumor volume (TV) is one of the main reported factors determining the outcome of treatment in head-and-neck carcinomas. In this study, the prognostic impact of TV was explored in the context of a randomized trial ... -
A radionuclide dosimetry toolkit based on material-specific Monte Carlo dose kernels
(2009)Objective We sought to develop a user-friendly dosimetry toolkit that should aid the improvement of the quality of radionuclide therapy, which is critically dependent on patient-specific planning of each treatment. Methods ... -
A review of PET normalization: striving for count rate uniformity
(2013)The advent of PET instrumentation signaled the beginning of a new perspective in nuclear medicine diagnostic imaging. PET systems rely on several corrections that must be applied in order to establish accurate and reliable ... -
The role of Doppler Perfusion Index as screening test in the characterization of focal liver lesions
(2008)Purpose. Doppler Perfusion Index (DPI) has been used in the detection of overt liver metastatic disease. In the present prospective Study we evaluated the use of DPI in the differential diagnosis of liver tumours. Materials ... -
Vascular injuries in laparoscopic cholecystectomy: An underestimated problem
(2006)Background: Bile duct injury is a severe complication of laparoscopic cholecystectomy and many reports focus on this topic, especially regarding the long- term success of repair of these injuries. There is some concern, ...
