Cardiovascular Magnetic Resonance Teaching Network

The article introduces a novel teaching approach allowing time-effective teaching as well as an ongoing quality control. The aim is to enable CMR in all settings – hospitals of different sizes as well as in outpatient departments. [...]

Aneurysm, cavernous carotid artery

A small mass lesion is noted within the left cavernous sinus on both CT and MR (axial imaging), with CT revealing enhancement therein. MRA confirms this to be an aneurysm, with the DSA provided for comparison (from an initial balloon test occlusion study). This 12 mm aneurysm of the cavernous segment of the internal carotid […] [...]

MAGNETOM Aera – Combining Throughput and Highest Quality MR Angiography in an Optimized Clinical Workflow

This paper shows how the simultaneous use of multipurpose loop coils in MRI allows high-resolution musculoskeletal studies with increased contrast and specificity for assessing muscles, tendons, ligaments, joints, and cartilage. Dr. Ferrer presents a number of different daily patient routine examinations, including specifically evaluation of the carpal bones, the thumb metacarpals, the metacarpals, the distal inter-phalangeal joints, the elbow and ankle. [...]

Assessment and Classification of Peripheral Vascular Anomalies by Time-Resolved MRA using TWIST.

Vascular malformations (VM) are complex lesions present in various anatomical locations with a variety of clinical manifestations. Time-resolved MRA combined with parallel imaging and echo sharing schemes offer a reasonable alternative to more invasive diagnostic methods such as digital subtraction angiography (DSA) in evaluation of VMs. MRI is becoming the imaging modality of choice in assessing morphological issues regarding VMs. Time-resolved MRA can play an important role in characterizing these lesions and can influence therapeutic decision-making.

Multiple Arterial Stenoses

This 63-year-old man presented with a longstanding history of peripheral arterial occlusive disease, hypertension, diabetes, coronary artery disease, prior myocardial infarction, crossover bypass, and renal artery stenosis with increasing leg pain. [...]

Dilatative Arteriopathy

This 76-year-old man presented for diagnostic angiography with a longstanding history of dilatative and occlusive arteriopathy, hypertension, coronary artery disease and a popliteal aneurysm. Clinically an occlusion of the femoral-popliteal bypass to the right PIII segment was known. [...]

Metastatic Melanoma

This 36-year-old patient presented in December 2006 with a suspicious mole on the right lower leg which was surgically removed. Histopathology demonstrated a malignant melanoma. 2.5 years later the patient presented with an inguinal lymph node metastasis on the right side detected on lymph node dissection. MRI was ordered to further evaluate the right leg on which additional cutaneous lesions were noted. [...]

Contrast Enhanced MRA of Dissection of the Carotid Artery

This 69-year-old man presented to the angiography department with a single episode of amaurosis fugax 6 months ago. Since that time he has been treated with thrombocyte aggregation inhibitors. Clinical symptomatology includes headaches and vertigo. [...]

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). [...]

Contrast Enhanced MRA of the Renal Arteries, with Renal Artery Stenosis

This 64-year-old man presented with an increased serum creatinine level (2.77 mg/dL) and significant asymmetry of renal size (reduced on the right) on ultrasound. The past medical history was pertinent for prior stenting of the right renal artery. [...]

MRA – False Aneurysm of the Renal Artery

This 71-year-old man presented to the emergency room with a fever up to 39°C and a general decline in his state of health. Two weeks previously, he underwent a partial resection of the right kidney due to suspected renal cell carcinoma, that turned out to be an hemorrhagic cyst. [...]

Contrast Enhanced MRA of a Pelvic Arteriovenous Malformation

This 43-year-old woman presented to the angiography department three years ago with pain in the lower abdomen. She underwent resection of an intrauterine fibroma in 1997 and a C-section in 2002. In September 2005, the question was raised regarding a possible malformation of iliac vessels on the left side. [...]

Arteriovenous Malformation

This 43-year-old female presented to clinic with a severe headache and neck neck pain for the last two weeks. This was associated with intermittent mental status changes. [...]

Continuous table movement MRA for diagnosis of generalized atherosclerotic disease

This 48 year old woman presented to the department of vascular surgery due to recurrent pain in both legs. She suffers from hypertension, hyperlipidemia and coronary artery disease. She has previously been diagnosed with a high-grade stenosis of the right internal carotid artery and occlusion of the left internal carotid artery, andis as well status post dilatation and stenting of the circumflex coronary artery. Additional relevant vascular disease and surgery include occlusion of the right subclavian artery, aortobifemoral bypass grafting due to high-grade stenosis, and occlusion of the common, external and internal iliac arteries on both sides. [...]

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. [...]
