OBJECTIVES: To develop and validate an artificial intelligence (AI) system for measuring and detecting signs of carpal instability on conventional radiographs. MATERIALS AND METHODS: Two case-control datasets of hand and wrist radiographs were retrospectively acquired at three hospitals (hospitals A, B, and C). Dataset 1 (2178 radiographs from 1993 patients, hospitals A and B, 2018-2019) was used for developing an AI system for measuring scapholunate (SL) joint distances, SL and capitolunate (CL) angles, and carpal arc interruptions...

BACKGROUND: Little data exists on the association of missed care opportunities (MCOs) in children referred for nuclear medicine/nuclear oncology imaging examinations and socioeconomic disparities. OBJECTIVE: To determine the prevalence of MCOs in children with lymphoma/leukemia scheduled for fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) and the impact of sociodemographic factors and Child Opportunity Index (COI)...

Breast cryoablation is a minimally invasive image-guided percutaneous procedure to treat fibroadenomas and early-stage breast cancer utilizing liquid nitrogen or argon gas to create extremely cold temperatures that devitalize targeted tissue. Although more long term data are needed, this outpatient procedure is well tolerated and carries minimal risks, including non-target thermal injury that can be mitigated by careful planning and proper technique. Building a sustainable breast cryoablation service in a radiology practice poses several practical considerations, such as training proceduralists, purchasing equipment, recruiting patients, and understanding the revenue cycle...

Pulmonary nodules may be an early manifestation of lung cancer, the leading cause of cancer-related deaths among both men and women. Numerous studies have established that deep learning methods can yield high-performance levels in the detection of lung nodules in chest X-rays. However, the lack of gold-standard public datasets slows down the progression of the research and prevents benchmarking of methods for this task. To address this, we organized a public research challenge, NODE21, aimed at the detection and generation of lung nodules in chest X-rays...

INTRODUCTION: Hip fracture is a serious affliction that requires fast care and an X-ray examination, which are provided by an ambulance and a visit to the radiology department, respectively. If a well-functioning mobile X-ray service could be developed, by examining the patient in their own home, both the work strain of hospital workers and patient suffering could be reduced. The purpose of this study was to determine if the mobile X-ray service could be a supplement to the fast-track process that is utilised by the ambulance service...

By training nurses and midwives on the basics of obstetric ultrasound, high-risk pregnancies in remote Nepalese villages can be identified and triaged. American radiology residents traveling to Nepal can improve their real-time, hands-on ultrasound scanning skills while learning the intricacies of practicing medicine in a low- and middle-income country. Global outreach work is increasing in popularity among US radiologists, emphasizing the importance of training radiology residents in point-of-care ultrasound...

BACKGROUND: Most imaging examinations use ionising radiation which causes biological effects on the body. For this reason, only justified examinations should be requested by adequately completing the radiology request form (RRF) by clinicians. The RRF allows radiographers and radiologists to assess if the benefit outweighs the risk associated with medical radiation exposure. Inadequately or incorrectly filled RRFs leads to unnecessary radiation exposures, imaging errors, and delays in performing the examination...

RATIONALE AND OBJECTIVES: A novel three-day radiology course, PRIMER, directly preceding medical students' clinical year, was created and assessed. The required course consisted of large group lecture sessions, small group breakout sessions, and individual assignments. Though early exposure to radiology has been described in preclinical anatomy curricula, few schools offer immersive experiences to radiology as a direct predecessor to the wards. MATERIALS AND METHODS: An identical survey was distributed prior to and at the completion of the PRIMER course...

BACKGROUND: In boys with Duchenne muscular dystrophy (DMD), initiation of bisphosphonate is recommended upon identification of moderate or severe vertebral fractures, even if asymptomatic. Clear radiological reporting is important for consistency of clinical interpretation and management. OBJECTIVES: To audit radiology reports of spine imaging for vertebral fracture assessment in DMD, and assess potential impact on diagnosis and management. MATERIALS AND METHODS: Lateral thoracolumbar spine imaging (71 lateral spine radiographs and 13 lateral dual energy absorptiometry spine image) in 84 boys with DMD performed across two centres...

Bronchiolitis obliterans syndrome (BOS) is a non-infectious pulmonary complication that can occur in patients who have undergone allogeneic bone marrow transplantation (BMT). BOS is characterized by the irreversible narrowing and obstruction of bronchi, resulting in severe respiratory distress and poor outcomes. This case report focuses on the complex management of a patient with a multifaceted medical history. A 20-year-old man was initially diagnosed with precursor B lymphoblastic lymphoma and subsequently underwent allogeneic BMT...

BACKGROUND: On February 6, 2023, an earthquake occurred in Kahramanmaras, Turkey, resulting in loss of life, injuries, and the displacement of thousands of people. The aim of this study is to determine the factors affecting amputation and fasciotomy decisions in patients with crush syndrome, along with clinical laboratory parameters. MATERIALS AND METHODS: The study included patients over 18 years of age who presented with crush injuries and exhibited systemic symptoms...

Angiosarcoma is an uncommon cause of soft tissue malignancy, accounting for approximately 2% of all soft tissue sarcomas. Of these, epithelioid angiosarcoma represents a morphologic subtype, where the malignant endothelial cells demonstrate a predominantly or exclusively epithelioid appearance. Overall, epithelioid angiosarcoma shares similar imaging characteristics to conventional angiosarcoma including a T1 hypointense to isointense and T2 hyperintense mass, which demonstrates avid enhancement, serpentine feeding vessels, and overlying skin thickening on MRI...

Breast cancer is one of the most common malignancies worldwide. Traditional treatment options for breast cancer include surgery, radiation therapy, and chemotherapy. However, cryoablation, a minimally invasive technique, has emerged as a promising alternative for the treatment of early-stage breast cancer. This article aims to provide an overview of cryoablation, focusing on incorporation into practice, patient selection, procedural technique, imaging follow-up, post-treatment radiopathological findings, and current and ongoing research in the field...

Pronator syndrome is a median nerve entrapment neuropathy that can be difficult to diagnose due to its variable presentation and objective findings. Neurolymphomatosis is an uncommon disease in which malignant lymphocytes infiltrate central or peripheral nerve endoneurium and is often missed for prolonged periods prior to diagnosis. We present a rare case of pronator syndrome and anterior interosseous nerve palsy due to neurolymphomatosis that was occult on initial MRI in spite of the presence of a median nerve mass discovered intra-operatively during neurolysis...

Sclerosing epithelioid fibrosarcoma (SEF) occurring as a primary bone tumor is exceptionally uncommon. Even more rare are cases of SEF that show morphologic overlap with low-grade fibromyxoid sarcoma (LGFMS). Such hybrid lesions arising within the bone have only rarely been reported in the literature. Due to their variegated histomorphology and non-specific radiologic features, these tumors may pose diagnostic difficulties. Herein we describe three molecularly confirmed primary bone cases of sclerosing epithelioid fibrosarcoma that demonstrated prominent areas showing the features of LGFMS and with areas resembling so-called hyalinizing spindle cell tumor with giant rosettes (HSCTGR)...

Analysis of relations between objects and comprehension of abstract concepts in the surgical video is important in AI-augmented surgery. Yet, building models that integrate our knowledge and understanding of surgery remains a challenging endeavor. In this paper, we propose a novel way to integrate conceptual knowledge into temporal analysis tasks using temporal concept graph networks. In the proposed networks, a knowledge graph is incorporated into the temporal video analysis of surgical notions, learning the meaning of concepts and relations as they apply to the data...

Here we present a case of a patient with breathlessness and cough admitted to the COVID ward. Chest radiography demonstrates findings consistent with lobar collapse, particularly, left upper lobe collapse, giving rise to the 'Luftsichel sign'. This sign has been described in the literature highlighting the importance of recognition and prompt further investigation.

This article explores the growing role of minimally invasive locoregional therapies in the multidisciplinary treatment of primary and metastatic breast cancer. Factors contributing to the expanding role of ablation for primary breast cancer include earlier diagnosis when tumors are small and increased longevity of patients who are poor surgical candidates. Cryoablation has emerged as the leading ablative modality for primary breast cancer due to its wide availability, lack of need for sedation, and ability to monitor the ablation zone...
