Artificial intelligence improves radiologist workflow and assessment of image quality accuracy.

Increasing imaging volumes and workflow pressures make consistent image quality assessment (IQA) challenging for radiologists in routine clinical practice. Artificial intelligence (AI) systems have recently been introduced to support quality control tasks, yet real-world evidence on their impact on radiologist workflow and diagnostic performance remains limited. Therefore, it is of interest to assess the effect of AI-IQA module of PACS/worklist on radiological workflow and accuracy in identifying suboptimal CT/MRI tests. Workflow (IQA time, TTFR and TAT) and IQA performance (sensitivity, speci…

Radiologic-Dermatologic Atlas of Commonly Encountered Skin Abnormalities for the Breast Radiologist.

Breast radiologists are frequently consulted for evaluation of patients with concerns related to skin changes of the breast. A broad spectrum of dermatologic conditions can manifest on the skin of the breast, the chest wall, and the axilla, including those with benign, malignant, infectious, and inflammatory causes. These conditions often pose a diagnostic challenge for breast radiologists as they may be associated with nonspecific or absent imaging findings. Moreover, such cases may fall outside the traditional scope of breast imaging training, potentially contributing to diagnostic uncertain…

Image-Guided Interventions for Intercostal Neuralgia: What the Radiologist Needs to Know.

Nerve blocks are excellent adjuncts to multimodal systemic analgesia in patients needing complex pain management, often producing days, weeks, or months of pain-free periods. Pain often debilitates patients with significant disruption to quality of life. Intercostal nerve injection and ablations are very useful procedures in patients suffering from pain caused by trauma, tumour, or inflammation. Traditionally done using anatomical landmarks, these procedures have been associated with a higher rate of complications. When imaging modalities (such as ultrasonography or computed tomography (CT)) a

Measuring Radiologist Workload After AI Triage in Breast Cancer Screening.

Artificial intelligence triage can sharply reduce the number of human readings in breast cancer screening. Reading count, however, does not show how much radiologist time is saved or whether work shifts to arbitration, consensus, or other tasks. We propose a session-level reporting standard based on total active human interpretation minutes per 1000 women screened, work shifted elsewhere in the pathway, and diagnostic outcomes, together with a matched-session design to measure these effects directly.

Left-sided portal hypertension: what an interventional radiologist can offer?

Left-sided portal hypertension (LPH) refers to increased splenic venous pressure caused by splenic vein stenosis or occlusion. Pancreatitis is the leading cause of LPH. Typically, LPH remains asymptomatic, but it can lead to life-threatening hemorrhage from ruptured fundal varices in about 10% of patients. Further, it may be complicated by hypersplenism. Interventional radiology plays an essential role in LPH patients with failed endoscopic treatment. Variceal embolization is an effective salvage measure in bleeding gastric varices, but it carries a risk of recurrence and worsening of hyperspl

BOA: A CT-Based Body and Organ Analysis for Radiologists at the Point of Care.

PURPOSE: The study aimed to develop the open-source body and organ analysis (BOA), a comprehensive computed tomography (CT) image segmentation algorithm with a focus on workflow integration. METHODS: The BOA combines 2 segmentation algorithms: body composition analysis (BCA) and TotalSegmentator. The BCA was trained with the nnU-Net framework using a dataset including 300 CT examinations. The CTs were manually annotated with 11 semantic body regions: subcutaneous tissue, muscle, bone, abdominal cavity, thoracic cavity, glands, mediastinum, pericardium, breast implant, brain, and spinal cord.

Fibrous Dysplasia of the Temporal Bone: a Demanding Entity for Radiologists and ENT Surgeons.

Fibrous dysplasia (FD) is a rare, benign, chronic, slowly progressive bone disorder characterized by the replacement of normal bone and bone marrow by fibrous tissue, leading to deformity, pain and functional impairment. It was considered a disease of unknown etiology, uncertain pathogenesis and diverse histopathology. It was later discovered that was caused by a non-heritable activating mutation in the á-subunit gene of the stimulatory G-protein coding gene. Temporal bone involvement is the least frequently reported type, especially in children. The purpose of the current manuscript was to re

Magnetic resonance urography of congenital abnormalities - what the radiologist needs to know.

Congenital abnormalities of the kidney and urinary tract include a wide range of malformations ranging from asymptomatic to life-threatening conditions. Although pediatric urogenital system imaging is based on the use of US (pre- and postnatal), voiding cystourethrography and scintigraphic study, magnetic resonance (MR) urography plays a fundamental role in the classification and management of congenital abnormalities of the kidney and urinary tract, giving an overview of the different clinical pictures, thanks to its panoramicity and high anatomical detail. In fact the anomalies of the urinar

The role of contrast fluoroscopy in modern day oesophageal imaging: A radiologist's perspective.

There has been a slow but steady decline in the frequency of contrast fluoroscopic studies performed all over the world, including oesophagography. This trend is attributed to the increasing availability of endoscopy, computed tomography (CT), and magnetic resonance imaging (MRI). Other diagnostic modalities that are continually supplanting oesophagography are manometry and oesophageal pH monitoring. As a result, contrast oesophageal imaging as a diagnostic modality is gradually being relegated to the background by both the radiologists and other physicians. The aim of this paper is to conside…
