This article describes pioneering electronic medical record (EMR) embedded tools to assess and support each diverse patient's digital health literacy. METHODS: We designed and validated a rapid EMR-embedded Digital Health Engagement Tool (DHET) to assess each patient's digital literacy in English and Spanish...

The rapid evolution of artificial intelligence (AI), particularly in deep learning, has significantly impacted radiology, introducing an array of AI solutions for interpretative tasks. This paper provides radiology departments with a practical guide for selecting and integrating AI solutions, focusing on interpretative tasks that require the active involvement of radiologists. Our approach is not to list available applications or review scientific evidence, as this information is readily available in previous studies; instead, we concentrate on the essential factors radiology departments must consider when choosing AI solutions...

INTRODUCTION: Introduction: Pellegrini-Stieda syndrome, characterized by medial collateral ligament (MCL) calcification or ossification, often follows a history of trauma. While rare, its distinct radiographic features pose diagnostic challenges. Conservative treatments are effective for many, but surgical intervention is necessary when they fail. CASE REPORT: A 31-year-old male with knee pain and stiffness, an inability to extend his knee, and a fixed flexion deformity...

Dietrich's disease, also known as Mauclaire's disease, is a rare condition characterized by avascular necrosis of the metacarpal heads, predominantly affecting adolescents. This case report aims to elucidate the diagnostic process and management of Dietrich's disease in adolescents. A 15-year-old male adolescent presented with left ring finger metacarpophalangeal joint pain and restricted range of motion following a remote history of sports-related trauma. Clinical examination revealed tenderness and limited flexion at the affected joint...

A pulmonary artery aneurysm (PAA) is a rare condition. It is treated in various ways, depending on its location and size. Herein, we describe the preoperative diagnosis of a PAA that was resected by segmentectomy. A 44-year-old female underwent CT, which revealed a 15-mm saccular protrusion in the right pulmonary artery and was diagnosed with PAA. The patient was initially observed without requiring further treatment, but a gradual increase in size led to therapeutic intervention. Because the PAA was located just peripheral to the right A8 bifurcation, embolization using interventional radiology was deemed too difficult...

Akin osteotomy is commonly used to correct hallux valgus interphalangeus (HVI) deformity. The preferred implant for fixation remains an area of debate, often influenced by the surgeon's inclinations and expertise. This review compares the outcomes of contemporary fixation methods utilized in Akin osteotomy. PubMed served as the primary electronic database for the search. The interventions encompassed the use of screw(s), staple(s), and suture(s). The participants considered were adults aged 18 and above, undergoing Akin osteotomy either as a primary procedure or as an adjunct...

A 52-year-old male presented to the emergency room with acute abdominal pain. Imaging determined acute appendicitis, with an incidental finding of a renal mass. The biopsy was positive for renal cell carcinoma, and the patient underwent simultaneous appendectomy and nephrectomy. Postoperatively, the patient developed hypoxia at night with exertion, requiring oxygen supplementation. The remainder of his vital signs were stable. Due to renal function, a ventilation/perfusion (V/Q) scan was conducted, which showed a high probability of pulmonary embolism (PE)...

BACKGROUND: Point of care ultrasound (POCUS) is specific for acute cholecystitis (AC), but surgeons request radiology imaging (RI) prior to admitting patients with POCUS-diagnosed AC. OBJECTIVES: We sought to determine the test characteristics of POCUS for AC when performed and billed by credentialed emergency physicians (EPs), the accuracy rate of RI when performed after POCUS, and the time added when RI is requested after POCUS demonstrates AC. METHODS: We performed a dual-site retrospective cohort study of admitted adult ED patients who had received biliary POCUS from November 1, 2020 to April 30, 2022...

KEY CLINICAL MESSAGE: Giant cell tumor of bone (GCT) is a rare neoplasm which often presents as a lytic lesion in the epiphyseal region of long bones and which are usually accompanied by pain, swelling, and restricted movement. ABSTRACT: Giant cell tumor of bone (GCT) is a rare neoplasm that affects individuals in their third and fourth decades of life. Clinically, it often presents as a lytic lesion in the epiphyseal region of bones, notably the distal femur and proximal tibia...

Meckel's diverticulum is the most prevalent congenital anomaly of the gastrointestinal tract, identified in 2% of the population according to autopsy studies. Most patients remain asymptomatic throughout their lives and are typically diagnosed when complications arise. The diagnosis can be challenging, but imaging is crucial for promptly identifying and distinguishing it from other conditions that have similar clinical manifestations. A 13-year-old male was admitted with a 5-day history of rectal bleeding. The patient continued to experience painless gastrointestinal bleeding, indicating the performance of a Tc-99m pertechnetate scintigraphy or Meckel's scan...

Tibial exostosis, also known as osteochondroma, is a common benign bone tumor found predominantly in adolescents and young adults. Vascular complications associated with this tumor, such as arterial occlusion and pseudoaneurysm formation, are rare but can lead to significant morbidity if not promptly diagnosed and managed. We present a case of a 25-year-old patient who presented with thrombosis of the left popliteal vein and a painless swelling in the popliteal fossa. Radiographic and CT angiography revealed an exostosis on the proximal tibia causing arterial occlusion and venous compression...

Stenosis of the portal vein is one of the main complications after hepatobiliar and pancreatic surgery, with a reported incidence of 19.6% after pancreaticoduodenectomy and 3% after liver transplant. It is associated with the intraoperative resection of the portal vein, local recurrence of the primary tumor and radiotherapy. The portal lesion secondary to bile drainage catheter insertion is extremely rare or unusual, with few cases described in the literature. This article describes 2 cases: the first of a male patients 49 years old post-operative to liver transplant with partial portal thrombosis and stenosis of the mesoportal joint, and the second a female patient 50 years old with history of cholecystectomy, exploration of the bile duct and placement of Kehr "T" tube with secondary portal lesion...

Kartagener's Syndrome is a rare autosomal recessive genetic condition, that affects the structure and function of cilia and includes a condition of situs inversus, chronic sinusitis, and bronchiectasis associated sometimes with infertility. A young patient who had a long-time fever, cough, and infertility after a clinical evaluation performed a chest X-ray and a CT scan that revealed the unexpected condition of Situs Inversus Totalis (SIT). Imaging also showed bronchiectasis and sinusitis: all findings consistent with Kartagener's syndrome, confirmed a second time by the genetic test...

Vein of Galen malformation (VGM) is a rare congenital, uncommon intracerebral vascular anomaly rarely complicated with the development of brain abscess as secondary to primary infection or after endovascular treatment. We report a very rare finding of a vein of Galen aneurysm associated with a large brain abscess at the time of diagnosis. A 12-year-old boy with a high-grade fever, severe headache, and recurrent episodes of convulsions came into the radiology department of Kassala Advanced Diagnostic Center...

Choledocholithiasis, characterized by the presence of stones in the common bile duct, poses significant challenges in clinical management, particularly when the stones are massive. While endoscopic methods are often effective in stone removal, complications such as the impaction of foreign bodies like Dormia baskets can occur. These complications may necessitate alternative approaches, including surgical intervention, highlighting the importance of exploring innovative interventional techniques. We report on an 89-year-old patient presenting with massive choledocholithiasis, involving complete filling of the intra- and extrahepatic bile duct system with large stones up to a maximum of 2 cm...

This study presented a model applied for potential risk assessment in an interventional radiology setting. The model of potential risk assessment (MARP) consisted of the creation of a scale of indicators ranging from 0 to 5. The radiation levels were categorized according to gender, kind of procedure, value of kerma air product (Pka), and accumulated radiation dose (mGy). The MARP model was applied in 121 institutions over 8 y. A total of 201 656 patient radiation doses (Dose-area product and accumulated kerma) data were launched into the system over time, with an average of 22 406 doses per year...

Here, we describe two patients with juvenile xanthogranuloma (JXG) manifesting with Langerhans cell histiocytosis (LCH)-associated neurodegenerative disease (ND)-like radiological findings. One patient showed typical radiological abnormalities at onset, which worsened with progressing central nervous system symptoms 7 years after LCH-oriented chemotherapy. Another showed spontaneous regression of clinical symptoms, with a transient radiological change 1 year after salvage chemotherapy for recurrence of JXG...

METHODS: This is a retrospective study of patients aged 14-50 years with a first diagnosis of medium to large PSP before and after March 2019 in a tertiary ED. Medical record and radiology database review were used to identify demographic, clinical and radiological data...

INTRODUCTION: Arteriovenous grafts (AVGs) serve as an alternative to native arteriovenous fistulas (AVFs) in the context of hemodialysis patient life planning. AVGs are more susceptible to developing outflow stenosis (due to intimal hyperplasia), thrombosis, and infections. However, an often overlooked contributor to AVG failure is cannulation damage. The objective of this paper is to assess the impact of cannulations on AVGs. We aim to establish a classification of AVG damage by comparing clinical data and ultrasound images with microscopic morphological findings obtained from explanted grafts...
