MRI evidence suggests that CAM impingement is more common in the elite ice hockey athlete in comparison with non-athletes. However, as this is a pilot study examining findings in asymptomatic individuals, there is a need for a longitudinal prospective cohort study. In keeping with this, sufficient, long-term follow-up is required to assess at what point, if any, these subjects with radiological findings become symptomatic.

Level 4, retrospective case series.

The results of this study differ from previously published data by demonstrating substantial agreement between readers in multidetector-row CT assessment of the tumor, mesorectal fascia, and lymph nodes. With the exceptions of mesorectal fascia in the distal rectum and the distance from the nodes to mesorectal fascia, other evaluated parameters were assessed with moderate and substantial agreement between multidetector-row CT and MRI. However, our findings suggest that multidetector-row CT does not correlate well enough with MRI findings to replace it in rectal cancer staging.

The utility of magnetic resonance imaging (MRI) in the selection, procedure planning, and follow-up of patients undergoing arterial embolization for uterine fibroids is reviewed. Advantages of MRI over ultrasound include multiplanar imaging capability, a larger field of view, increased spatial resolution, improved anatomic detail, and the ability to detect other pelvic disorders. MRI can assess fibroid viability by detecting contrast agent enhancement. Magnetic resonance angiography has a useful role in evaluation of pelvic vasculature. Magnetic resonance parameters such as T1 and T2 relaxation times and diffusion-weighted characteristics have an emerging role in predicting outcome before and after embolization. MRI may be used to evaluate technical success and to image potential complications after embolization.

With the evaluated CAD system, it is relatively simple and fast to check all detected findings and decide if they represent true PE. However, high false-negative results demand technologic improvement, to increase the sensitivity of the system. It is anticipated to become a promising supplement to the work and eyes of the radiologist in detecting PE on pulmonary CT angiography.
