Magnetic Resonance Elastography of the Liver: A Single-Institution Review of Cases Performed in a 5-Year Interval
This study aimed to assess the diagnostic accuracy of magnetic resonance elastography (MRE) in detecting hepatic fibrosis and determining clinically relevant stiffness cutoff values per stage of fibrosis.
Methods
This retrospective study assessed 1488 hepatic MRE evaluations performed at a single institution for 5 years. Mean liver stiffness measurements were collected from 282 patients who had an MRE study within 1 year of histopathologic analysis. Areas under receiver operating characteristic curves were calculated for each stage of fibrosis with nonparametric ordinal measures of accuracy, and Youden Index was det...

Computed Tomography Imaging Characteristics: Potential Indicators of Epidermal Growth Factor Receptor Mutation in Lung Adenocarcinoma
Purpose
The purpose of this study was to investigate the correlation between computed tomography imaging characteristics in lung adenocarcinoma and epidermal growth factor receptor (EGFR) mutations.
Methods
A total of 124 patients with lung adenocarcinoma and known EGFR mutation status were collected in this retrospective study. Computed tomography quantitative parameters of each tumor, including total volume, total surface, surface-to-volume ratio (SVR), average diameter, maximum diameter, and average density, were determined using computer-aided detection software. The correlation between the EGFR mutation sta...

Structured Reporting of Computed Tomography Examinations in Post–Lung Transplantation Patients
Objective
The aim of this study was to evaluate the benefits and potential of structured reports (SR) for chest computed tomography after lung transplantation.
Methods
Free-text reports (FTR) and SR were generated for 49 computed tomography scans. Clinical routine reports were used as FTR. Two pulmonologists rated formal aspects, completeness, clinical utility, and overall quality. Wilcoxon and McNemar tests were used for statistical analysis.
Results
Structured reports received significantly higher ratings for all formals aspects (P (Source: Journal of Computer Assisted Tomography)

The Past, Present, and Future (Liquid Biopsy) of Serum Tumor Markers in Lung Cancer: A Primer for the Radiologist
Lung cancer continues to be a major cause of death throughout the world. The ability to both accurately diagnose lung cancer in its early stages and monitor response to treatment is essential to reducing the morbidity and mortality associated with the disease. Serum tumor markers have been identified as potential biomarkers that may aid in lung cancer diagnosis and surveillance. These markers, when combined with cross-sectional imaging, may result in more robust screening and surveillance protocols. The future role of serum tumor markers in lung cancer includes the advancement of “liquid biopsies,” in which peripheral ...

Magnetic Resonance Imaging Evaluation of Distance Between Adenoid Tissue and Internal Carotid Artery in Children With Adenoid Hypertrophy
Objectives
In the present study, we investigated the distance between adenoid tissue and internal carotid artery (ICA) in children with adenoid hypertrophy by magnetic resonance imaging.
Methods
Cranial magnetic resonance images of 200 children with adenoid hypertrophy between the ages of 5 and 15 were included. In group 1 (5–9 years of age), there were 100 children, and in group 2 (10–15 years of age), there were 100 children. In both groups, adenoid thickness, adenoid/nasopharynx) ratio, and superior, middle, and inferior adenoid-ICA distances were measured.
Results
Adenoid thickness is significantl...

Enlarged Parathyroid Glands on Trauma Computed Tomography: Frequency and Assessment for Possible Primary Hyperparathyroidism
Conclusions
Parathyroid glands were enlarged in 3% of our cohort. Although PHPT likelihood seems to increase with gland size, definitive determination requires both serum calcium and serum parathyroid hormone. (Source: Journal of Computer Assisted Tomography)

Application of Flat-Panel Volume Computed Tomography to Evaluate Cerebral Hemorrhage After Mechanical Thrombectomy of Acute Embolic Stroke of the Anterior Circulation
Objective
The aim of the study was to evaluate cerebral hemorrhage (CH) and contrast media leakage (CML or commonly synonymous with “contrast staining”) differentiation on flat-panel volume computed tomography (FPVCT) after intra-arterial mechanical thrombectomy.
Methods
We evaluated patients with hyperattenuation on FPVCT after intra-arterial mechanical thrombectomy between 2018 and 2021 by multiple parameters on CT angiography, FPVCT, CT, and/or magnetic resonance imaging.
Results
The CH (n = 43) versus CML (n = 24) groups revealed: (1) regional anatomical characteristics (preserved and distorted): ...

Evaluation of Computed Tomography Attenuation Value of Proximal Femoral Marrow to Diagnose and Differentiate Hematologic Malignancies, Myelofibrosis, and Aplastic Anemia
Objective
The aim of this study was to diagnose hematologic diseases using computed tomography (CT) number of proximal femoral marrow.
Methods
The average CT number of marrow in hematologic diseases was measured on the caudal side of the greater trochanter.
