Impact of optical coherence tomography angiography review strategy on detection of choroidal neovascularization

Conclusion: Review strategies for detection of CNV on OCTA were highest using the manual segmentation method as compared to both the automated report and continuous slab descent methods. Although the manual segmentation method had a higher rate of detection, the practical aspects of the time required for segmentation make this method challenging in routine clinical practice.

Conclusion: DAVFs are treatable lesions that rarely occur in the pediatric age group. They are associated with serious neurological morbidity. When suspected, they should be immediately diagnosed with magnetic resonance imaging/magnetic resonance angiography, and formal angiography. Prompt neurosurgical and neuroradiological/ endovascular opinions and intervention should be sought to provide and the best treatment strategy. PMID: 32494372 [PubMed]

In this study, we reevaluated data sets from patients undergoing CT examinations because of suspected pulmonary embolism and compared doses and diagnostic results of the standard protocol to the additional modern CT subtraction technique. Two groups of single-blinded radiologists were provided with CT data sets from 50 patients. One group (G1) had access to full datasets including CT subtraction with perfusion map. The other group (G2) only evaluated conventional CT angiography. Results were compared to final clinical diagnosis. Dose length product (DLP) of CT angiography was compared to CT subtraction technique, which con...

MR imaging hardware and software improvements have led to new applications for contrast-enhanced and noncontrast-enhanced magnetic resonance angiography in the abdomen and pelvis. Higher magnetic field strength MR imaging scanners have greater signal-to-noise ratio and contrast-to-noise ratio, which is used to improve spatial resolution or temporal resolution for these techniques. New noncontrast-enhanced sequences offer high-resolution magnetic resonance angiography without contrast and provide additional hemodynamic information. Magnetic resonance angiography is particularly well suited to imaging patients with chronic m...

Abstract The full spectrum of COVID-19 is still emerging, although several studies have highlighted that patients infected with the novel coronavirus can potentially develop a hypercoagulable state. However, several aspects related to the incidence and pathophysiology of the association between COVID-19 and pulmonary embolism are not well established. Here, we present a case of a patient with COVID-19 who developed acute pulmonary embolism. Clinical and laboratory data and findings of non-enhanced CT indicate possibility of acute pulmonary embolism, and support the decision to proceed with computed tomography pulmonary ang...

In Gene Roddenberry's science fiction series Star Trek, any scene involving the sick or injured reliably featured the Tricorder. This trusty futuristic medical device was passed quickly over the ailing crewmember's body to arrive at a rapid and accurate diagnosis. The idea of a rapid whole body scanner was laughable in the 70's, but the concept is becoming much more reasonable today. Our medical history is teeming with examples of progression from slow, invasive diagnostics to rapid, noninvasive tools.

BACKGROUND Patients with blunt cerebrovascular injuries are at risk of thromboembolic stroke. Although primary prevention with antithrombotic therapy is widely used in this setting, its effectiveness is not well defined and requires further investigation. The aim of this study was to evaluate the utility of magnetic resonance imaging (MRI)–detected ischemic brain lesions as a possible future outcome for randomized clinical trials in this patient population. METHODS This prospective observational study included 20 adult blunt trauma patients admitted to a level I trauma center with a screening neck CTA showing ex...

The objective of this study is to investigate the use of PET-CT scan with 18F-fluorodeoxyglucose (18F-FDG) as a method to predict outcomes in patients with Takayasu arteritis (TAK), as well as to analyze associations between 18F-FDG PET-CT findings with disease relapses, sustained remission, new angiographic lesions, ischemic events, and changes in therapy for TAK. At baseline assessment, 36 TAK patients underwent 18F-FDG PET-CT scan and maximal standardized uptake value (SUVmax) in arteries  ≥ 1.3 was predictive for clinical disease activity. Thirty-two TAK patients were then followed-up for a median 83.5...

ConclusionThe positive CT-PA rate varied significantly between seasons. Smoking was a predictor of positive CT-PA results. These findings may assist in developing interventions for improving the utilization of CT-PA scans to avoid unnecessary exposure of patients to radiation.Clinical trial registrationN/A
