Angiographic findings of pulmonary arterial involvement in Behcet's Disease: Do they correlate with symptoms and acute phase response?

Introduction: Behcet's disease (BD) is a chronic inflammatory disorder with arterial vasculitis. Although, pulmonary artery aneurysm (PAA) is accepted as the prototypic arterial disorder, an increasing presence of pulmonary artery thrombosis (PAT) with or without aneurysms was also reported in recent studies. In this study, we aimed to describe computed tomography pulmonary angiography (CTPA) findings of pulmonary involvement and its correlation with symptoms and acute phase response in BD.

Radiological Quantification of Sarcopenic Obesity and its Role in Chronic Liver Disease Severity.

Rationale And Objectives: To define sarcopenic obesity (SaO) among chronic liver disease (CLD) patients via CT and MRI, and assess its impact on liver disease severity.

Materials And Methods: CLD patients referred from the Gastroenterology and Hepatology Department diagnosed as chronic hepatitis B (N:101), cirrhosis (N:110), and hepatocellular carcinoma (N:169) with available information on body height, weight, Child-Pugh and MELD scores within 2 weeks of CT or MRI scanning were included in the study. Cross-sectional examinations were retrospectively evaluated for skeletal muscle index (SMI) and visceral adipose tissue area (VATA).

Does shortening the duration of radiotherapy treatment in breast cancer increase the risk of radiation pneumonia: A retrospective study.

Randomized studies evaluating hypofractionation and conventional fractionation radiotherapy treatments (RT) in patients with breast cancer have shown that hypofractionation achieves similar results to conventional fractionation in terms of survival and local control rates. It has also been shown that their long-term toxicities are similar. This study aimed to evaluate the effects of hypofractionated radiotherapy (H-RT) and conventional radiotherapy (C-RT) on lung toxicity and identify factors affecting this toxicity in patients with breast cancer.

Optimal plan target in cases with locally advanced nasopharyngeal cancer: Comparison of VMAT, IMRT, hybrid, and tomotherapy results.

Purpose: In locally advanced nasopharyngeal cancer (NC), the spread of the disease, proximity to critical structures, and high dose requirement for tumor control may complicate the treatment plan. In this study, VMAT/IMRT/hybrid/tomotherapy plans were made to reach the safest and most effective dose distribution for each of the patients and the results were compared.

Methods: Double volumetric-modulated arc therapy (VMAT) and 7- and 9-field intensity-modulated radiation therapy (IMRT) plans were made to 21 locally advanced NCs with Varian Trilogy System.

New grading system for post-COVID-19 pulmonary fibrosis based on computed tomography findings.

Background: There is currently no objective computed tomography (CT)-defined grading system for coronavirus disease (COVID-19)-related pulmonary fibrosis. We propose a CT-based radiological scale that adapts the histological fibrosis scale to pulmonary fibrosis CT findings, to evaluate possible predictive factors for the degree of fibrosis in these patients.

Methods: A new radiological fibrosis grading system was created based on existing histological fibrosis scales.

Assessment of peritoneal thickness using CT in relation to dialysis adequacy in peritoneal dialysis patients.

Studies assessing peritoneal thickness by CT in peritoneal dialysis (PD) patients are lacking. In this study, we aimed to investigate the association between peritoneal thickness as measured by CT and dialysis adequacy with peritoneal membrane characteristics in PD patients. Ninety-four PD patients were enrolled.

Contribution of Magnetic Resonance Imaging in Determining Lumpectomy Cavity in Breast Radiotherapy.

Background: Accurate localization of the lumpectomy cavity is important for breast cancer radiotherapy after breast-conserving surgery (BCS), but the LC localization based on CT is often difficult to delineate accurately. The study aimed to compare CT-defined LC planning to MRI-defined findings in the supine position for higher soft-tissue resolution of MRI.

Methods: Fifty-nine breast cancer patients underwent radiotherapy CT planning in supine position followed by MR imaging on the same day.

Angular Dependence of Solar Cell Parameters in Crystalline Silicon Solar Cells Textured with Periodic Array of Microholes.

Surface texturing is an indispensable way of increasing absorption in solar cells. In order to properly characterize the effect of texturing, the angular dependence of the incidence light should be addressed. This is particularly important when the actual application where the incidence angle of the sunlight varies during the day is considered.

Surgical Clips in Breast-conserving Surgery: Do they Represent the Tumour Bed Accurately?

Introduction: Radiotherapy after Breast-Conserving Surgery (BCS) is a standard treatment for breast cancer. Currently, surgical clips are used to determine the tumour bed before radiotherapy planning. This study aimed to evaluate the migration of these clips on mammograms.

Optical properties of CuZnSnSe thin films and identification of secondary phases by spectroscopic ellipsometry.

We apply spectroscopic ellipsometry (SE) to identify secondary phases in CuZnSnSe (CZTSe) absorbers and to investigate the optical properties of CZTSe. A detailed optical model is used to extract the optical parameters, such as refractive index and extinction coefficient in order to extrapolate the band gap values of CZTSe samples, and to obtain information about the presence of secondary phases at the front and back sides of the samples. We show that SE can be used as a non-destructive method for detection of the secondary phases ZnSe and MoSe and to extrapolate the band gap values of CZTSe phase.

How Many of the Biopsy Decisions Taken at Inexperienced Breast Radiology Units Were Correct?

Objective: In this study, we aimed to determine the need for biopsy in patients referred from other clinics for the performance of biopsy with the suspicion of breast cancer.

Materials And Methods: 112 patients were included in the study. It was decided that their biopsies be performed following examinations in other clinics and they presented to the breast radiology unit of our hospital for a second opinion.

Efficacy of single voxel 1H MR spectroscopic imaging at 3T for the differentiation of benign and malign breast lesions.

Purpose: The aim of our study was to evaluate the effect of 1H Magnetic Resonance Spectroscopy (MRS) in differentiating breast lesions.

Materials And Methods: Single voxel 1H Magnetic Resonance Spectroscopy (1H-MRS) was performed with 3T magnet in 45 women. The choline cut off point was set semi-quantitavely.

Comparison of transcutaneous, arterial and end-tidal measurements of carbon dioxide during laparoscopic cholecystectomy in patients with chronic obstructive pulmonary disease.
