Mixed one-bit compressive sensing with applications to overexposure correction for CT reconstruction [PDF]

open access: yesarXiv, 2017
When a measurement falls outside the quantization or measurable range, it becomes saturated and cannot be used in classical reconstruction methods. For example, in C-arm angiography systems, which provide projection radiography, fluoroscopy, digital subtraction angiography, and are widely used for medical diagnoses and interventions, the limited ...

Posterior Epistaxis Presenting as Upper GI Bleeding in A Healthy 21‐Year‐Old Patient: A Case Report

open access: yesClinical Case Reports, Volume 13, Issue 4, April 2025.
ABSTRACT A 21‐year‐old Palestinian woman experienced recurrent hematemesis and melena over 7 months, requiring multiple hospital admissions and blood transfusions. Despite extensive investigations, the bleeding source remained undetermined until a posterior nasal bleed was suspected. Flexible rhinoscopy revealed a dilated sphenopalatine artery, and she

Mitigating Early Phosphatidylserine Exposure in a Tmem30a‐Dependent Way Ameliorates Neuronal Damages After Ischemic Stroke

open access: yesMedComm, Volume 6, Issue 4, April 2025.
The ischemic penumbra is the hypo‐perfused brain tissue at risk of progressing to infarction but is still salvageable if re‐perfused. Wu et al. demonstrate increased plasma Annexin V reduced PS exposure in a Tmem30a‐dependent way in the penumbra after stroke, consequently leading to a better neurological outcome.

CT material decomposition with contrast agents: Single or multiple spectral photon‐counting CT scans? A simulation study

open access: yesMedical Physics, Volume 52, Issue 4, Page 2167-2190, April 2025.
Abstract Purpose With the widespread introduction of dual energy computed tomography (DECT), applications utilizing the spectral information to perform material decomposition became available. Among these, a popular application is to decompose contrast‐enhanced CT images into virtual non‐contrast (VNC) or virtual non‐iodine images and into iodine maps.
