Despite the fact that OCT angiography (OCTA) does not technically qualify as multimodal imaging per se, it does offer several modes of visualization from a single scan, including an angiogram, a structural picture, and en face imaging with boundary specific segmentation. The use of OCTA can assist doctors in communicating to patients with geographic atrophy who are susceptible to exudation the necessity for routine follow-up. Clinicians can rule out artifacts by analyzing the flow overlay on the OCTA cross-section. If the flow isn’t where it should be for the illness, it’s probably an artifact.

Per Svenningsson, MD, PhD, a neurologist with expertise in Parkinson’s disease, will serve as the multicenter trial’s principal investigator. He previously oversaw a clinical study using montelukast (Singulair) tablets to treat PD. The multicenter trial is anticipated to begin between July and September. During the 18-month trial, participants will be randomized to receive either montelukast VersaFilm or a placebo film. IntelGenx plans to use the results to enhance the clinical development of its montelukast VersaFilm for Parkinson’s.

A prospective cohort study of 629 patients with non-MRI-conditional ICDs from 2003 to 2013, including 813 MRIs, concludes that the devices continue to function properly after MRI.

The assessment of response to radiation-based therapies can be complicated by persistent or changing imaging features, and this field of study is still in active development even though imaging-based response assessment systems have been validated for the evaluation of response to ablative locoregional therapies. Research is still needed to address the shortcomings of current imaging criteria for evaluating tumor response to these novel techniques, despite the increased application of radiation-based local-regional therapies for the treatment of HCC following technological advancements and a better understanding of tumor biology.

In a study of 37,887 men 50 to 60 years old, those with PSA of >= 3 ng/ml underwent MRI imaging of the prostate and were randomized to systematic biopsy plus targeted biopsy or MRI-targeted biopsy only. MRI-directed targeted biopsy reduced the risk of overdiagnosis by half but did delay detection of intermediate-risk tumors in a small proportion of patients.

Although both devices were highly reliable in detecting signs of early diabetic retinopathy (DR), and the interrater reliability of DR stage between the devices was “almost perfect” in the 7 standard fields (7SF) and total gradable areas (TGA), the Clarus 700 (Zeiss) provided better visualization of the inferonasal field than the Daytona P200T (Optos).
