Imaging of Diseases of the Cranial Nerves: Tips and Tricks

This article focuses on common problems and pitfalls in MRI of pathologies of cranial nerves. It provides an introduction to helpful sequences and post processing techniques. To familiarize the reader with cranial nerve imaging, examples of the normal anatomy as well as typical pathological cases are shown. [...]

Arteriovenous malformation

22 year old man with left sided sensory seizures. The seizures are of focal onset, typically affecting the left arm and shoulder, with radiation to the entire left side within 2-3 seconds. He describes the seizures as an electric burning feeling that “is not pain”. [...]

An Overview of Imaging Techniques for the Carotid Bifurcation

Because it has been proven that there is a link between the development of nephrogenic systemic fibrosis (NSF) and the application of high volumes of magnetic resonance (MR) contrast agents in patients with impaired renal function, interest in non-contrast-enhanced techniques for MR angiography has experienced a renaissance. This set of images presents 5 different techniques for imaging the carotid bifurcation, one of the most critical and commonly diseased vascular regions within the entire arterial system. Except one (D), for best comparability, all exams were acquired with the same spatial resolution of 0.9 x 0.9 x 0.9 mm3 at 3 T (Magnetom Verio, Siemens Medical Solutions). [...]

New Non-Contrast MR Techniques (for MR angiography and tissue perfusion)

NATIVE enables excellent non-contrast MR angiographic imaging, with reproducible results. This new software/scan approach is particularly important given that the use of intravenous contrast media has come under recent increased scrutiny. Of relevance, the gadolinium chelates (and specifically the less stable agents in this class), which are used as MR contrast agents, have been linked to a condition called Nephrogenic Systemic Fibrosis (NSF) that can occur in patients with renal insufficiency. [...]

syngo Native – Non Contrast MR Angiography Techniques

With the need to carefully consider the risk versus benefit of contrast agent administration, following the advent of Nephrogenic Systemic Fibrosis (NSF), as well as the need to perform cost effective MR studies, there is a demand for improved methods for performing MR angiography using intrinsic rather than extrinsic contrast mechanisms. [...]

syngo NATIVE TrueFISP in the Assessment of the Transplanted Kidney

When imaging patients with impaired renal function that have recently undergone transplant surgery, one approach is to use a completely non- invasive method, without the use of a gadolinium chelate, and thus without the potential risk of NSF. In this article the effectiveness of TrueFISP with selective inversion recovery preparation, now known as syngo NATIVE TrueFISP, is shown. This technique from a diagnostic point of view appears equivalent to low dose contrast-enhanced angiography, providing a low-risk method for the initial evaluation of the transplanted kidney. [...]
