Scintigraphic Evaluation of Traumatic Splenic Lesions in Children
Acta Radiologica - Tập 29 Số 1 - Trang 121-125 - 1988
U. Erasmie, W. Mortensson, Ulf Persson, K. Lännergren
Ninety-eight children with recent blunt abdominal trauma which initially evoked clinical suspicion of splenic injury were examined with colloid scintigraphy of the spleen and the liver using multiple imaging views and with abdominal survey. Nineteen children were, in addition, examined with tomographic scintigraphy. The clinical findings and the course of the disorder were reanalysed. Scintigraphy... hiện toàn bộ
Brain Metastases — Comparison of Gadodiamide Injection-Enhanced MR Imaging at Standard and High Dose, Contrast-Enhanced CT and Non-Contrast-Enhanced MR Imaging
Acta Radiologica - Tập 36 Số 3 - Trang 300-306 - 1995
Per Åkeson, E.-M. Larsson, Doris Tove Kristoffersen, E. Jonsson, S. Holtås
MR Imaging with Gadolinium in Patients with and without Post-Lumbar Puncture Headache
Acta Radiologica - Tập 40 Số 2 - Trang 135-141 - 1999
Jan Hannerz, K. Ericson, Hanne Pernille Bro Skejø
Purpose: To study frequency and extent of meningeal enhancement in patients with and without post-lumbar puncture headache (PLPH) with cerebral MR with Gd-DTPA. Material and Methods: Ten consecutive patients with PLPH and 9 consecutive patients without PLPH were included in the study. Nine of the PLPH patients were reinvestigated when the PLPH was over and all non-PLPH patients during the week aft... hiện toàn bộ
Polyorchidism: sonographic and magnetic resonance image findings
Acta Radiologica - Tập 46 Số 7 - Trang 769-771 - 2005
Ali Yusuf Öner, Çağdaş Şahin, S. Pocan, Eşref Kızılkaya
Polyorchidism is a rare congenital anomaly frequently associated with maldescent testis, hernia, and torsion. Reports in the literature show an increased risk of testicular malignancy in the presence of polyorchidism. This entity has characteristic sonographic features and the diagnosis is often made on the basis of sonography. Magnetic resonance imaging might also be used for the diagnosis, but i... hiện toàn bộ
Hepatic Portal Venous Gas
Acta Radiologica - Tập 36 Số 4-6 - Trang 377-380 - 1995
Carsten Schulze, U Blum, K. Haag
In a prospective investigation the sensitivity of conventional radiography, sonography, color Doppler flow imaging (CDFI) and CT in the detection of hepatic portal venous gas (HPVG) was compared in 7 patients with different diagnoses. For the identification of HPVG sonography, CDFI and CT have a higher sensitivity than conventional radiography. CT, however, was the most suitable method to identify... hiện toàn bộ
Traumatic cervical injuries in ankylosing spondylitis
Acta Radiologica - Tập 45 Số 2 - Trang 222-226 - 2004
P. Nakstad, Andrès Server, Roger Josefsen
Purpose: To demonstrate the importance of magnetic resonance (MR) and computed tomography (CT) in the evaluation of cervical traumas in patients suffering from ankylosing spondylitis. Material and Methods: Eleven patients with advanced ankylosing spondylitis were admitted to neurosurgical treatment after trauma to the neck region. All had neurological symptoms and were evaluated with plain X‐ray, ... hiện toàn bộ
Contrast medium dose-to-gfr ratio: a measure of systemic exposure to predict contrast-induced nephropathy after percutaneous coronary intervention
Acta Radiologica - Tập 49 Số 6 - Trang 658-667 - 2008
Ulf Nyman, Jonas Björk, Peter Aspelin, Giancarlo Marenzi
Background: The contrast medium (CM) dose-to-eGFR (estimated glomerular filtration rate) ratio has recently been advocated to express systemic exposure to CM in assessing the risk of contrast medium-induced nephropathy (CIN). Purpose: To evaluate how CIN risk might vary with decreasing eGFR at fixed CM-dose/eGFR ratios and other CIN risk factors, and to find a relatively safe CM-dose/eGFR ratio. M... hiện toàn bộ
Low-contrast-dose protocol in cardiac CT: 20% contrast dose reduction using 100 kVp and high-tube-current-time setting in 256-slice CT
Acta Radiologica - Tập 55 Số 5 - Trang 545-553 - 2014
Masafumi Kidoh, Takeshi Nakaura, Shinichi Nakamura, Shota Nakamura, Naritsugu Sakaino, Kazunori Harada, Sachiko Uemura, Yasuyuki Yamashita
Background The use of the smallest contrast dose is highly desirable in performing cardiac computed tomography (CT), especially for patients with cardiovascular diseases to prevent contrast-induced nephropathy. Purpose To evaluate the feasibility of 20% reduced contrast dose protocol in cardiac CT using 100 kVp and high-tube-current-time product setting. Material and Methods Fifty patients were sc... hiện toàn bộ
Dynamic MR imaging of liver metastases with Gd-EOB-DTPA
Acta Radiologica - Tập 41 Số 3 - Trang 255-262 - 2000
W Stern, Fritz Schick, Andreas F. Kopp, Peter Reimer, Kohkan Shamsi, Claus D. Claussen, Michael Laniado
Purpose: To assess liver and lesion enhancements by dynamic MR imaging after bolus injection of the hepatobiliary contrast agent gadolinium ethoxybenzyldiethylenetriamine-pentaacetic acid (Gd-EOB-DTPA) in patients with liver metastases and to compare the effect of different doses. Material and Methods: A randomized double-blinded trial with doses of 12.5, 25 and 50 µmol/kg Gd-EOB-DTPA was performe... hiện toàn bộ
MnDPDP for MR imaging of the liver
Acta Radiologica - Tập 38 Số 5 - Trang 638-642 - 1997
Ernst J. Rummeny, C. G. Torres, J C Kurdziel, G Nilsen, Bart Op de Beeck, B. Lundby
Purpose: To evaluate the diagnostic efficacy of mangafodipir trisodium (MnDPDP, Teslascan) as a new contrast agent for MR imaging of the liver based on an independent evaluation of the MR images from the European phase III studies. Material and Methods: MR imaging of the liver was done at 0.5–2.0 T in 17 European centres and included T1-weighted spin-echo and gradient-echo sequences before and aft... hiện toàn bộ
