MRA and US were found to be superior to the 3 clinical tests, and even the most reliable clinical test (the impingement) had a sensitivity of only 59%.
It shows clear outlines of the lumen of affected arteries, whereas MRA and US can demonstrate thickening of the vascular wall of the aorta and its major branches [ 2- 5].
Data on diagnostic accuracy of MRI, MRA and US were pooled for (1) full or partial RC tears, (2) full RC tears only, (3) partial RC tears only and (4) tendinopathy.
The results demonstrate that our method is capable of identifying the real vessel boundaries accurately for the CT, MRA, and US images, although they have complex shape and topology.
The diagnosis of TA is based on its suggestive clinical features and imaging methods such as conventional angiography, magnetic resonance angiography (MRA) and ultrasonography (US).
Experiments were performed using real vessel images with different modalities, including digital subtraction angiography (DSA) images, infrared image, computed tomography (CT) images, and MRA and ultrasonic (US) images of different parts of human body.
MRA also allowed us to visualize anterior and/or lateral translation of the femoral head, indicating substantial cartilage deficiency in the area of migration.
Excellent, or diagnostic, image quality was achieved for 100% of aortic segments on SSFP MRA, which allowed us to confidently evaluate all aortic disease with a diagnostic accuracy of 100% using CE-MRA as the reference standard.
The high and stable specificity across studies of the US, MRI and MRA leads us to recommend their uses for the confirmation of RC pathologies in patients already suspected of having those problems on the basis of clinical evaluation tests in acute cases where surgery might be considered rapidly or in situations where conservative treatments have failed.
All patients with TA were initially evaluated by magnetic resonance angiography (MRA) and vascular ultrasonography (US).
