1.Diffusion-weighted magnetic resonance imaging (DWMRI)  was shown to be both sensitive and specific for identification of pelvic lymph node metastases among patients with prostate or bladder cancer.  2. The inclusion of several additional imaging criteria in conjunction with DWMRI reduced the number of diagnostic errors and was associated with superior...

Image: PD 1. Whole-body diffusion-weighted MRI with ferumoxytol had comparable sensitivity and specificity to 18FDG-PET/CT scans in pediatric lymphoproliferative disorder and malignant sarcoma staging.  2. The use of IV ferumoxytol as contrast agent was not associated with significant adverse events.  Evidence Rating Level: 2 (Good)            Study Rundown: 18FDG-PET/CT...

Image: PD/Navy 1. Patients with mesorectal invasion of more than 5mm and sacral-side involvement (seen on MRI) demonstrated higher rates of local recurrence.   Evidence Rating Level: 2 (Good)  Study Rundown: Upper rectal cancers (URC), when compared to middle and lower rectal cancers, have a lower risk of local recurrence. This is because...

Image: PD  1. Prevalence of unruptured cerebral aneurysms (UCAs) detected by magnetic resonance aniography (MRA) in adults was found to be 7.0%.  Evidence Rating Level: 3 (Average)        Study Rundown: The prevalence of unruptured cerebral aneurysms (UCAs) have been previously been reported as 1-5% with an annual rupture rate of...

Image: PD  1. MRI-guided ultrasound thalamotomy improved essential tremor symptoms in a small group of patients.  2. A substantial subset of study subjects experienced sensory disturbances following treatment.  Evidence Rating Level: 2 (Good)  Study Rundown: This pilot study demonstrates that MRI-guided transcranial ultrasound thermo-ablation can induce lesions in the deep brain and improve...

Image: PD Exserohilum rostratum 1. MRI screening of patients receiving an injection of contaminated methylprednisone indicated that 21% had a clinically significant lesion.  2. Earlier detection of lesions presumably allows for earlier initiation of medical or surgical management of sequelae of fungal infection. Evidence Rating Level: 2 (Good)  Study Rundown: Contaminated methylprednisolone injections recently...

Image: PD 1. Functional MRI (fMRI) can reliably discern thermal pain based on a reproducible neurologic signature. 2. The signature was specific for physical pain (vs. social pain) and also reduced in a dose-dependent manner in response to infusion of remifentanil. Study Rundown: Pain is an unpleasant sensory and emotional experience that...
