Background: In this study, the flip technique was compared with the classical method in terms of procedural success and procedure time during ductal stent implantation (DSI) via the carotid artery in patients whose pulmonary blood flow is dependent on the vertical type of ductus arteriosus (DA).
Methods: Between January 2019 and June 2023, 40 patients (24 males, 16 females; mean age: 15.9±15.4 days; range, 1 to 68 days) with vertical ductus-dependent pulmonary circulation who underwent patent DA stent implantation via the carotid artery were included in the study. Patients were divided into two groups: those who underwent the flip technique (Group 1) and those who did not undergo the flip technique (Group 2). Data were retospectively compiled by reviewing patient files and catheter images.
Results: Demographic findings were similar in the groups. The distribution of the DA in terms of tortuosity index was also similar in the groups. The procedure was successful in 18 (90%) patients in Group 1 and 20 (100%) patients in Group 2. There was no procedure-related mortality in both groups. The frequency of procedure-related complications was similar. Procedure duration was 53.6±18.4 min in Group 1 and 41.5±9.1 min in Group 2; the difference was significantly lower in Group 2 (p=0.028). The shorter follow-up in Group 2 was attributed to the flip method starting to be used later in the clinic. During follow-up, stent dilatation was required in two patients in Group 1 and one patient in Group 2, and a second stent implantation was needed in one patient in Group 2. No significant difference was observed between the two groups in terms of reintervention.
Conclusion: The success rate of DSI using the carotid artery access is high with both the classical and the flip method in patients with vertical DA. However, the use of the flip technique could be preferred in terms of operator habituation, ergonomic use of the catheter, guidewires, and shorter procedure time.

Polymorphism, commonly denoting diverse molecular or crystal structures, is crucial in the natural sciences. In van der Waals antiferromagnets, a new type of magnetic polymorphism arises, presenting multiple layer-selective magnetic structures with identical total magnetization. However, resolving and manipulating such magnetic polymorphs remain challenging.

Background And Purpose: Magnetic Resonance Imaging is widely used to assess disease burden in multiple sclerosis (MS). This study aimed to evaluate the effectiveness of a commercially available k-nearest neighbors (k-NN) software in quantifying white matter lesion (WML) burden in MS. We compared the software's WML quantification to expert radiologists' assessments.

Purpose: Compressed Sensing (CS) is an emerging technique to accelerate MRI acquisitions. The aim of this study was to assess the reliability and accuracy of cartilage thickness measurements in the knee using a CS-enabled isotropic 3D Fast Spin-Echo (FSE) sequence on a 3-T MRI scanner.
Methods: Twenty-eight tibial condyle sections were collected from 14 adult patients who underwent total knee arthroplasty.

Significance: Optimal meibography utilization and interpretation are hindered due to poor lid presentation, blurry images, or image artifacts and the challenges of applying clinical grading scales. These results, using the largest image dataset analyzed to date, demonstrate development of algorithms that provide standardized, real-time inference that addresses all of these limitations.
Purpose: This study aimed to develop and validate an algorithmic pipeline to automate and standardize meibomian gland absence assessment and interpretation.
