NON-CONTRAST MAGNETIC RESONANCE UROGRAPHY

Magnetic Resonance Urography in Patients with Non- Contributory Intravenous Urography

Magnetic Resonance Urography (MRU) is increaingly replacing Intravenous Urography (IVU) which has been the traditional modality for uro-imaging. However, the effectiveness and advantages of this new and costly modality need to be proven before defining its place in the uro-radiological armamentarium. We conducted a prospective study to assess the role of MRU in 100 consecutive cases where IVU w...

Synthesis and evaluation of nanoglobule-cystamine-(Gd-DO3A), a biodegradable nanosized magnetic resonance contrast agent for dynamic contrast-enhanced magnetic resonance urography

Dynamic contrast-enhanced magnetic resonance imaging has been recently shown to be effective for diagnostic urography. High-resolution urographic images can be acquired with T1 contrast agents for the kidney and urinary tract with minimal noise in the abdomen. Currently, clinical contrast agents are low molecular weight agents and can rapidly extravasate from blood circulation, leading to slow ...

contrast enhanced magnetic resonance imaging in sacroiliitis

conclusion fs t2 w and ce fs t1 w sequences of axial planes were the most useful sequences in determination of active sacroiliitis. therefore, in patients with renal failure or allergy to contrast media, fs t2 wi can be obtained to detect active sacroiliitis. objectives the aim of this retrospective study was to assess the value of different magnetic resonance imaging (mri) sequences in evaluat...

Magnetic resonance urography in children – when and why?

BACKGROUND The aim of the study was to determine the potential of magnetic resonance urography (MRU) in evaluation of paediatric urinary tract pathologies. PATIENTS AND METHODS.: Twenty-one paediatric urological patients were evaluated with T1, T2 prior and after and 3D gradient echo sequences after the contrast administration. Results were compared with findings obtained with ultrasound which...
