Fahr's disease is defined as the accumulation of bilateral idiopathic calcification in the basal ganglia, dentate nucleus, and centrum semiovale. The coexistence of Fahr's disease and intracranial tumors is extremely rare, with only five cases documented in the literature. This study aimed to present a rare case, discussing both similarities and differences with previously reported cases.

Purpose: Urolithiasis is a common health problem with a high recurrence rate, and effectively balancing follow-up with intervention is important for patient safety. In this context, our study aims to identify criteria that can predict the likelihood of spontaneous passage (SP) of ureteral stones.

Methods: A retrospective analysis was performed on 2,773 patients who presented to our hospital with renal colic over a 4-year period.

Background: Post-contrast T1-MPRAGE sequence has been used in routine tumor imaging at many centers for decades. Meningiomas may be accompanied by leptomeningeal as well as parenchymal collaterals. In this study, we aimed to demonstrate the collaterals that may accompany meningiomas on postcontrast T1-MPRAGE imaging and to investigate their relationship with location, size, histologic features, adjacent bone, and parenchymal changes.

Purpose: This study aimed to evaluate the effectiveness of artificial intelligence (AI) in diagnosing focal nodular hyperplasia (FNH) of the liver using magnetic resonance imaging (MRI) and compare its performance with that of radiologists.

Methods: In the first phase of the study, the MRIs of 60 patients (30 patients with FNH and 30 patients with no lesions or lesions other than FNH) were processed using a segmentation program and introduced to an AI model. After the learning process, the MRIs of 42 different patients that the AI model had no experience with were introduced to the system.

Objective: To assess the frequency of unrecognized myocardial infarction and identify additional ischemic conditions, as well as to evaluate the efficacy of cardiac magnetic resonance imaging (CMRI) in risk groups, comparing the imaging findings with electro-cardiographic (ECG) and laboratory data in patients with stage 5 chronic kidney disease, also known as end-stage renal disease.

Materials And Methods: This was a prospective single-center study involving 20 patients who were referred to our radiology department to undergo CMRI between June 2010 and December 2011. Resting left ventricular functions and (early and late) myocardial contrast enhancement were assessed in all patients.

We examined the case report written by Ke , describing a rare clinical case. In this editorial, we would like to emphasize the differential diagnosis of rectal masses through a rare case. We describe a case of ameboma, which manifested itself as a mass in the rectum in terms of imaging and rectoscopic features, in an immunocompetent patient who had complaints of constipation and rectal bleeding for weeks.

Radiography is a field of medicine inherently intertwined with technology. The dependency on technology is very high for obtaining images in ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). Although the reduction in radiation dose is not applicable in US and MRI, advancements in technology have made it possible in CT, with ongoing studies aimed at further optimization.

Background: Determination of platybasia and basilar kyphosis are significant parts of routine cranial magnetic resonance (MR) interpretations. These situations may explain a patient's symptoms or may be associated with other anomalies.

Aim: To indicate the interobserver and intraobserver reliability of the skull base angles (SBA) (Koenigsberg standard) and modified SBA (mSBA) measurement techniques.

Alveolar echinococcosis (AE) primarily manifests in the liver and exhibits characteristics resembling those of slow-growing malignant tumours. Untreated infection can be lethal. By infiltrating the vascular systems, biliary tracts, and the hilum of the liver, it might lead to various problems.

Background And Objective: The aim of this study is to evaluate the effectiveness of apparent diffusion coefficient (ADC) values in predicting pathologic subtypes and grade in non-small-cell lung cancer (NSCLC).

Materials And Methods: From January 2018 to March 2020, 48 surgically diagnosed NSCLC cases were included in this study. To obtain ADC values, ADC maps were constructed, and a region of interest was put on the tumor.

Objective: Our aim was to investigate the effectiveness of the dual-energy computed tomography (DECT) virtual noncalcium (VNCa) technique in avascular necrosis (AVN) for detecting bone marrow edema (BME) and staging.

Methods: This prospective study included adult patients diagnosed with unilateral or bilateral femoral head AVN between January 2023 and December 2023, who had magnetic resonance imaging (MRI) and DECT. Two participants were excluded from the study due to undergoing surgical procedures during the period between the scans.

Objectives: The objective of this study is to prospectively assess the effectiveness of shoulder magnetic resonance (MR) arthrograms with positional manoeuvres in detecting posterior synovial folds.

Methods: Two radiologists independently assessed all axial MR arthrograms in internal rotation, neutral position, and external rotation for the presence of a posterior synovial fold. The diagnostic performances of the MR arthrograms were then compared, with results validated through arthroscopy.

Shear wave elastography (SWE) has become popular in clinical practice for many diseases. However, there is not adequate research on spleen-related diseases. This study aimed to investigate the potential of quantitative values obtained through SWE in evaluating spleen pathologies in the pediatric population and to demonstrate its performance to differentiate splenomegaly-related diseases.

Article Synopsis
  • The study investigates potential drug interactions between favipiravir, a treatment for COVID-19, and radiocontrast agents used in diagnostic imaging, which had not been previously researched.
  • Data from 1,046 patients showed that older patients are at a higher risk for drug interactions, with 4% of cases experiencing possible interactions.
  • Most interactions were mild, but notable side effects included increased creatinine and transaminase levels, as well as increased nausea and vomiting.

Background: Magnetic resonance imaging (MRI) of the cervical spine is one of the routine MRI scans of the cervical region in investigating spinal disc pathologies, spinal stenosis, and the detection of spinal lesions, which are the major parameters to be evaluated in this examination.

Purpose: The authors of this study are focused on a different aspect of cervical MRI, revealing the incidences and reporting rates of extraspinal incidental findings.

Methods: A total of 1000 patients (324 males, 676 females, mean age 47 ± 14) who had undergone an MRI of the cervical spine were enrolled in this study.

Purpose: Awareness of normative values of extra orbital structures would provide useful information to interpret the radiological images better and use them for diagnostic purposes. This study aimed to reveal the average values of major extraocular structures measured on magnetic resonance images.

Methods: In this retrospective cross-sectional study, magnetic resonance (MR) images of 256 orbits of 128 patients were re-interpreted regarding the measurements of major orbital structures.

The present study was designed to evaluate whether AuNPs (gold nanoparticles) synthesized with the Cynara scolymus (CS) leaf exert protective and/or alleviative effects on arsenic (As)-induced hippocampal neurotoxicity in mice. Neurotoxicity in mice was developed by orally treating 10 mg/kg/day sodium arsenite (NaAsO) for 21 days. 10 µg/g AuNPs, 1.

Article Synopsis
  • This study examined the relationship between the SP-ET index (the patella-femoral trochlea distance ratio) and chondromalacia patella (CP) using MRI data from 348 knees belonging to 308 patients.
  • Two reviewers analyzed these measurements, finding excellent agreement on the values calculated, and concluded that patients with CP had significantly higher SP-ET index values compared to those without CP.
  • The findings suggest a strong correlation between the SP-ET index and the severity of CP across different demographics, indicating its potential as a useful diagnostic tool.
