Editorial [Hot Topic: Abdominal and Pelvic Magnetic Resonance Imaging (MRI), the New Frontiers (Guest Editor: Michael R. Torkzad )]
More LessWhen MRI was introduced, it was first used for neurological and musculoskeletal imaging. The body, due to its size, complex movements, and even more complex pathology remained an elusive domain for MRI. As time went on, this changed quickly as pioneers began exploring what we can do with MRI of abdomen and pelvis. Today MRI is the best non-invasive imaging modality for most abdominal and pelvic diseases. Some of t Read More

The Clinical Perspective on Value of 3D, Thin Slice T2-Weighted Images in 3T Pelvic MRI for Tumors
Authors: Michael R. Torkzad, Johan Wikstrom, Tomas Hansen, Antonina Bergman, Tomas Bjerner and Hakan AhlstromPelvic imaging is undergoing rapid changes due to increased use of 3-Tesla (3T) magnetic resonance imaging (3T MRI). One of the advantages of 3T could be the possibility for thin section 3-dimensional (3D) imaging which could improve accuracy and at the same time reduce the need for multi-planar imaging needed for conventional T2 imaging (TSE). In the following text we review the advantages of 3D thin section imaging for Read More

Diffusion-Weighted Imaging in Abdominal Oncology
Authors: Zhen Li, Susanne Bonekamp and Ihab KamelDiffusion-weighted magnetic resonance imaging (DWI) can provide functional information on a cellular level by measuring water diffusion values. DWI is sensitive to changes in the micro diffusion of water and the apparent diffusion coefficient (ADC) is an indicator of the movement of water within the tissue. In abdominal oncology, DWI has been successfully used for the features of liver and prostate lesions, particularly for th Read More

Diffusion-Weighted Magnetic Resonance Imaging in Pelvic Cancer
Authors: N. M. deSouza, S. Kyriazi and E. SalaDiffusion-weighted MRI exploits intrinsic tissue contrast generated by movement of water within tissues over distances of around 1-20 microns. These distances are travelled by water within microcapillaries or in the extracellular space as a result of thermally driven random motion, where movement is limited by structural interfaces such as cell membranes. Diffusion-weighted imaging thus reflects microcapillary perfusion Read More

Magnetic Resonance Imaging of the Cervix, and its Relevance to the Revised International Federation of Gynecology and Obstetrics (FIGO) Staging
Authors: Penelope Moyle and Evis SalaThe International Federation of Gynecology and Obstetrics (FIGO) staging system is the oldest and most widely used system for treatment planning and prognosis in cervical cancer. On the 1st of June 2009 the FIGO committee introduced the revised staging of cervical carcinoma updating the previous staging of 1988. Although FIGO staging system does not include radiology in the staging of cervical cancer, the committee enc Read More

MRI of Focal Liver Lesions
By Nils AlbiinMagnetic resonance imaging, MRI has more advantages than ultrasound, computed tomography, CT, positron emission tomography, PET, or any other imaging modality in diagnosing focal hepatic masses. With a combination of basic T1 and T2 weighted sequences, diffusion weighted imaging, DWI, and hepatobiliary gadolinium contrast agents, that is gadobenate dimeglumine (Gd-BOPTA) and gadoxetic acid (Gd-EOB), most live Read More

Imaging of Complications After Laparoscopic Hepatobiliary Surgery
Authors: Audun Elnaes Berstad, Hans-Jorgen Smith and Andreas AbildgaardLaparoscopic hepatobiliary surgery is a popular, blossoming procedure. As a consequence, a range of complications are seen, some of these are rare and not well known. As a tertiary center of hepatobiliary disease, we review our experiences with CT and MR imaging of a spectrum of complications after such surgery.

Functional Renal MRI
Authors: Pottumarthi V. Prasad and Muhammad HaqueThe article provides a broad overview of functional MRI methods for evaluating the kidney. While the major function of the kidney is excretion and maintenance of homeostasis, functional MRI methods include several techniques that provide tissue characterization above and beyond anatomical depiction. We have divided the review under two major sub-sections based endogenous and exogenous contrast mechanisms. Diffusion Read More

MRI of the Small and Large Bowel
More LessCombining the advantages of lack of ionizing radiation with excellent soft tissue contrast, magnetic resonance imaging (MRI) of the gastrointestinal tract has become a clinically accepted tool. Tumor and infectious disease as well as bowel inflammation can be easily visualized on MR images. This article describes current techniques of gastrointestinal MRI, points out particularities of bowel MRI at 3T, explains how to accurately anal Read More

Design and First Results of an Innovative and Dedicated Breast PET
In this work the design and preliminary clinical results obtained with an innovative and dedicated breast PET is presented. A geometrical study clearly pointed out the advantages of the prone position and the technique of hanging breast in comparison to the supine, conventionally used for other imaging modalities. Occult, multifocal and also lesions close to the pectoral muscle were depicted by means of the prone method. Read More

The Predictive Value of Vessel-Based Calcium Score in the Detection of Coronary Stenosis
Authors: Muzaffer Elmali, Serdar Demir, Okan Gulel, Cetin Celenk, Mehmet Selim Nural, Meltem Ceyhan and Yuksel BekThe aim of this study was to investigate the predictive value of vessel-based calcium (Ca) score in the detection of ≥%50 coronary stenosis. The results of 65 patients with typical chest pain or multiple cardiovascular risk factors who underwent coronary Ca scoring and catheter angiography were retrospectively evaluated. 260 coronary arteries were analysed and mean vessel-based Ca score was 179±17.0 (range 0-1729). In Read More
