Visualization of choroidal neovascularization using two commercially available spectral domain optical coherence tomography angiography devices
Conclusion: There was no significant difference in the size of the CNV lesion as measured on either commercially available spectral domain OCTA device. Both devices were comparable in their detection of CNV lesions on manual adjustment of segmentation lines. However, their automated segmentation algorithms need improvement to allow for accurate measurement of CNV lesions for routine clinical application.
A 67-year-old man with recurrent left lower lobe pneumonia and abscess was referred for a calcified lesion within the left chest, initially detected on non-contrast-enhanced computed tomography (CT) scan. CT angiography revealed an aneurysmal, aberrant left lower lobe pulmonary artery with scarred lung parenchyma (A). The aneurysm was bilobed with a 3.6-cm maximum diameter in the distal portion. In addition, the artery was aneurysmal at its origin from the descending thoracic aorta (A), just above the diaphragm.
Duplex ultrasound examination, computed tomography scans, and magnetic resonance angiography have traditionally been used as noninvasive methods to assess carotid stenosis severity. The degree of stenosis in asymptomatic patients has often been used as the main criterion to assess risk for plaque embolization and stroke. There has been an effort to find alternate methods to assess vulnerable plaques. This has included many modalities, including magnetic resonance imaging and other ultrasound techniques.

Conclusion: Choroidal microcirculation is impaired in SSc, even in patients without ophthalmological symptoms. Choroidal OCT and OCTA may offer additional biomarkers for SSc activity. PMID: 31526060 [PubMed - as supplied by publisher]

ConclusionStroke CT will continue to increase the out of hours work load for CT departments across the country especially with our ageing population. It is vital that services, particularly in level 3 stroke centres, are adequately equipped in terms of staffing to meet the highest standard of care in the management of acute stroke.
ConclusionPatients admitted to AMU with suspected TIAs had relevant imaging and tests completed as per guidelines. 89 % had US Carotid Dopplers which were on average done 33h from admission. 58% of patients had inpatient heart monitoring. The average length of stay was 3 days but three patients stayed in AMU for up to 5 days. Protected imaging slots for AMU would expedite investigations and reduce inpatient stay.
ConclusionsEven though FP-CT provides similar CBV values and reconstructed blood volume maps as CTP in cerebrovascular disease, additional studies are required in order to reliably compare its diagnostic accuracy with cerebral perfusion imaging.
ConclusionsIn a population of symptomatic patients, the majority of patients with extensive calcification had evidence of inducible myocardial ischemia on CTP. CAC score was the only independent predictor of inducible myocardial ischemia on CTP.
First magnetic particle imaging angiography in human sized organs by employing a multimodal ex vivo pig kidney perfusion system. Physiol Meas. 2019 Sep 13;: Authors: Molwitz I, Ittrich H, Knopp T, Mummert T, Salamon J, Jung C, Adam G, Kaul MG Abstract Objective Magnetic Particle Imaging (MPI) is a new, fast and three-dimensional imaging technique, which is considered promising for angiographies. As available MPI-scanners suffer from restricted spatial resolution and are mostly constructed for small animal imaging, no vessels within one organ have been depicted by MPI, yet. The purpose of this...
