Noise Reduction in Brain CT: A Comparative Study of Deep Learning and Hybrid Iterative Reconstruction Using Multiple Parameters.

Objectives: We evaluated the noise reduction effects of deep learning reconstruction (DLR) and hybrid iterative reconstruction (HIR) in brain computed tomography (CT).

Methods: CT images of a 16 cm dosimetry phantom, a head phantom, and the brains of 11 patients were reconstructed using filtered backprojection (FBP) and various levels of DLR and HIR. The slice thickness was 5, 2.

Prolonged Capillary Refill Time as an Early Sign of Compromised Circulation in an Infant With Supraventricular Tachycardia: A Case Report.

Capillary refill time (CRT) is a valuable clinical sign in pediatric assessment, particularly in evaluating circulatory status. We present a case of a one-month-old infant with supraventricular tachycardia (SVT), who demonstrated prolonged CRT, emphasizing the importance of this physical examination finding in the context of other signs of compromised circulation.

Triple-regulated conditionally replicating adenovirus for effective and safer treatment of peritoneal carcinomatosis.

There is no effective therapy for peritoneal carcinomatosis derived from gastric cancer. An ideal conditionally replicating adenovirus (CRA) that selectively replicates in and kills cancer cells has not been developed for gastric cancer-derived peritoneal carcinomatosis. Using our platform technology of CRA regulated and treating tumors with multiple factors (m-CRA), we generated two types of survivin-responsive m-CRAs, Surv.

Effects of organ dose modulation applied to a part of the scan range on radiation dose in computed tomography of the body.

In computed tomography (CT), organ dose modulation (ODM) reduces radiation exposure from the anterior side to reduce radiation dose received by the radiosensitive organs located anteriorly. We investigated the effects of ODM applied to a part of the scan range on radiation dose in body CT. The thorax and thoraco-abdominopelvic region of an anthropomorphic whole-body phantom were imaged with and without ODM.

Immediate foot reconstruction and revascularization of toes using an interposition superficial circumflex iliac artery perforator flow-through flap: A case report.

Foot injuries, particularly degloving injuries, can lead to segmental loss of neurovascular structures in the toes, making simultaneous reconstruction of both the foot and toes challenging. This case report presents a technique using the superficial circumflex iliac artery perforator (SCIP) flap for immediate reconstruction of the dorsal foot and revascularization of multiple toes. A 28-year-old man suffered a degloving injury on the dorsum of his foot resulting in a 9 × 6cm skin defect, open fracture dislocations, exposure of tendons, and neurovascular injury, which included a 6-7.
