Emergency radiology in displaced populations: imaging and practical challenges.

Migrants and refugees tend to use emergency departments as their primary source of care, leading to a substantial increase in emergency radiological imaging. Migrants and refugees have risk factors, such as low vaccination rates, poor hygiene, malnutrition, and inadequate self-care, which increase their risk of contracting infectious diseases. For example, the prevalence of tuberculosis among refugee populations in host countries is increasing, and imaging findings related to tuberculosis are frequently observed by radiologists.

Evaluating Cerebral Blood Flow among Patients Experiencing Premenstrual Syndrome with Headache using Duplex Ultrasonography.

Introduction: This study aimed to demonstrate the relationship between hemodynamic changes in head blood flow and headache during the premenstrual period in patients experiencing premenstrual syndrome.

Methods: Thirty-two female patients experiencing premenstrual headaches were prospectively examined using carotid and vertebral artery duplex ultrasonography during headache episodes in the premenstrual periods and headache-free periods across two consecutive menstrual cycles. The diameters and areas of both the carotid and vertebral arteries, along with systolic and end-diastolic velocities, pulsatility and resistivity indices, and volumetric flow rates, were measured using grayscale imaging.

DNA methylation-based analysis reveals accelerated epigenetic aging in giant cell-enriched adult-type glioblastoma.

Background: Giant cell (gc)-enriched glioblastoma (gcGB) represents a distinct histological variant of isocitrate dehydrogenase wild-type adult-type glioblastoma with notable enlarged mono- or multinuclear tumor cells. While some studies suggest a survival advantage for gcGB patients, the underlying causes remain elusive. GcGBs are associated with TP53 mutations, and gcs were shown to accumulate DNA double-strand breaks and show deficient mitosis, potentially triggering cellular senescence programs.

Pancreatic injury due to blunt trauma on CT: does retropancreatic fat tissue reduce the severity of pancreatic injury?

Background: Pancreatic injuries from blunt abdominal trauma have a high mortality rate, often accompanied by injuries to adjacent organs. This study aims to investigate the relationship between the size of retropancreatic adipose tissue and the severity of pancreatic and adjacent organ injuries in patients with pancreatic trauma.

Methods: We retrospectively screened computed tomography (CT) images of 34 patients (25 males, nine females, aged 13-69 years) and 34 controls (28 males, six females, aged 15-66 years) who suffered blunt abdominal trauma.

New Fully Automated Preparation of High Apparent Molar Activity Ga-FAPI-46 on a Trasis AiO Platform.

A large number of applications for fibroblast activation protein inhibitors (FAPI)-based PET agents have been evaluated in conditions ranging from cancer to non-malignant diseases such as myocardial infarction. In particular, Ga-FAPI-46 was reported to have a high specificity and affinity for FAP-expressing cells, a fast and high accumulation in tumor lesions/injuries together with a fast body clearance when investigated in vivo. Due to the increasing interest in the use of the agent both preclinically and clinically, we developed an automated synthesis for the production of Ga-FAPI-46 on a Trasis AiO platform.

Diagnostic Performance of Radiology Residents in Thoracic CT Imaging in Emergency Radiology During The COVID-19 Pandemic.

Background: During the COVID-19 pandemic, the workload of all radiologists and radiology residents, as well as other clinical physicians, has increased.

Introduction: This study aims to determine the diagnostic performance of radiology residents, who effectively contribute to the diagnosis of COVID-19.

Methods: The thoracic Computed Tomography (CT) images of 135 patients aged 20-83 diagnosed with COVID-19 were evaluated retrospectively by five radiology residents and a radiologist with 10 years of experience.

Evaluation of the chest computed tomography and hemogram data in patients with COVID-19: the importance of thymus.

Background/aim: To investigate the relationship between imaging findings and peripheral blood cell counts of COVID-19 patients and the degree of thymus fat involution of these patients.

Materials And Methods: Computed tomography (CT) images of 87 patients with COVID-19 positive through RT-PCR testing were evaluated retrospectively by two radiologists. Ground glass densities and other signs of viral pneumonia were recorded, lung involvement was scored quantitatively.

Does otosclerosis affect the dimensions of the facial canal and cochlear aquaduct?

Purpose: Our aim was to evaluate the relationship of the dimensions of the facial canal (FC) and cochlear aqueduct (CA) in otosclerosis (OS) with the type and severity of OS.

Methods: Two radiologists retrospectively evaluated temporal bone high-resolution computed tomography (HRCT) images obtained from 48 healthy individuals and 94 OS patients between January 2015 and July 2020. In the study group, the CA width, funnel base width, and funnel length, in addition to the FC transverse length, were measured in the axial plane.

Efficiency of Fat Suppression in T1-Weighted Inner Ear Magnetic Resonance Imaging: Multipoint Dixon Method Versus Hybrid Techniques.

Background: Temporal bone is a region where fat suppression is difficult due to the inhomogeneity of various structures with different molecular properties.

Introduction: We aimed to determine the most effective fat suppression sequence in order to increase the visibility of the inner ear region.

Materials And Methods: The hybrid techniques and T1-Weighted mDIXON images of 40 patients with Magnetic Resonance (MR) imaging of the inner ear were prospectively compared by two experienced radiologists in terms of fat suppression efficacy.

Sparsity of dendritic cells and cytotoxic T cells in tumor microenvironment may lead to recurrence in basal cell carcinoma.

Background: Antitumor immune response affects tumor growth. The effect of antitumor immune response on recurrence has been poorly studied in basal cell carcinoma (BCC).

Objectives: To investigate the effects of the peritumoral immune infiltrate on BCC recurrence.

Multiparametric MRI Evaluation of Developmental Venous Anomalies in the Brain: Association with Signal Changes on FLAIR in Patients with Multiple Sclerosis.

Background: Developmental venous anomalies (DVAs) can be determined on magnetic resonance imaging (MRI), and they may be associated with multiple sclerosis (MS) lesions.

Purpose: The objective was to evaluate the MRI findings of DVAs in the brain, to compare the prevalence of them between MS patients and control subjects, and to investigate the correlation of DVA-associated fluid-attenuated inversion recovery (FLAIR) hyperintensities and MRI-derived parameters between MS patients and control subjects having DVA.

Methods: Total 160 patients with a mean age of 45 ± 16 years who underwent multiparametric MRI including susceptibility-weighted imaging (SWI), diffusion-weighted imaging, 3D FLAIR, and contrast-enhanced imaging were included in this retrospective study.

Extranodal lymphoma of the head and neck: a pictorial essay.

Primary extranodal lymphoma is defined as a lymphoma at a solitary extranodal site, with or without involvement of the lymph nodes. The clinical and radiological features of extranodal lymphoma have been documented in recent studies. In this pictorial essay, we reviewed imaging findings of extranodal lymphoma in the head and neck region.

Quantitative Third Harmonic Generation Microscopy for Assessment of Glioma in Human Brain Tissue.

Distinguishing tumors from normal brain cells is important but challenging in glioma surgery due to the lack of clear interfaces between the two. The ability of label-free third harmonic generation (THG) microscopy in combination with automated image analysis to quantitatively detect glioma infiltration in fresh, unprocessed tissue in real time is assessed. The THG images reveal increased cellularity in grades II-IV glioma samples from 23 patients, as confirmed by subsequent hematoxylin and eosin histology.

Purpose: We aimed to assess the correlation between renal apparent diffusion coefficient (ADC) values measured by diffusion-weighted imaging (DWI) and the clinical stages of diabetic nephropathy.

Materials And Methods: DWI (b value, 0 and 600 s/mm2) was performed in 78 patients with clinically confirmed diabetic nephropathy (study group) and 22 volunteers without diabetes mellitus or any renal disease (control group). The mean ADCs were calculated from multiple region-of-interest circles positioned in the renal cortex.
