Gallery of uncommon orthopedic implants: a guide for emergency radiologist.

The purpose of this gallery of orthopedic implants was to provide a reference for emergency radiologists to quickly identify uncommon devices in the shoulders, hips, and extremities. The cases presented in this exhibit will include unusual arthroplasties and prostheses as well as bone graft implants (including allograft and autograft). Bone grafts are frequently used for the treatment of bone defects, which may be caused by trauma, infection, or avascularity. Autogenous cancellous, corticocancellous, or cortical bone grafts are often used, either free or vascularized. Alternative bone graft su…

[Typical questions from the rheumatologist to the ophthalmologist and cooperating radiologist].

Patients with rheumatic disorders may suffer from various acute or chronic ocular symptoms. In addition to pain and motility disorders, loss of vision, and irreversible deterioration of the eye may occur. Red eye, a symptom easily identified, can be a sign of rheumatic involvement, but can also have a variety of other causes. Dry eye is frequently present in rheumatic patients. It is always important that infections and masquerade syndromes are ruled out in the differential diagnoses of any ocular inflammation. In cases of ocular inflammation the ophthalmologist should determine the diagnostic

Causes of radiologists' deaths: a survey of 400 cases in the literature.

BACKGROUND: In their profession, radiologists use ionizing radiation, which has a negative effect on tissue and is a cause of various cancers and other diseases. OBJECTIVES: To determine the causes of radiologists' deaths in general and whether they are related with cancer as a cause of death. MATERIALS AND METHODS: The causes of 400 radiologists' deaths were analyzed retrospectively in this study based on descriptions available in the American Journal of Roentgenology from 1975 to 1999 and Radiology from 1970 to 1999, randomly chosen.

[Splenic abscesses. Their percutaneous treatment and the role of the interventional radiologist].

Percutaneous abscess drainage is not as common in the spleen as in other anatomical sites, probably because of an uncontrollable fear of bleeding. Five cases of intrasplenic abscess drainage are presented. A double-way 12/14-F vanSonnenberg catheter was percutaneously inserted under CT guidance in four patients and under US guidance in one patient. Orthogonal scout CT views were useful to check the correct positioning of the drainage. In three patients the maneuver was successful, with no recurrence at follow-up at 12, 16 and 24 months, respectively. In one patient with a splenic abscess due t

Variability Among Radiologists in Interpreting Low-Dose CT Lung Cancer Screens.

BACKGROUND: Lung cancer screening (LCS) with low-dose CT (LDCT) reduces lung cancer mortality, but false-positive tests remain a concern. Radiologist variability in interpreting LDCT scans may contribute to higher false-positive rates (FPRs). METHODS: Radiologists were identified from the LCS registry maintained by the ACR. Registry data were merged with Medicare files to create an LCS registry-Medicare database. Radiologists with ≥50 baseline or ≥50 postbaseline LDCT screens in the database were included in the analysis. The sensitivity and FPR were defined as the proportion of positive (Lun…

Maintaining a healthy work environment with hybrid and remote pediatric radiologists.

Providing hybrid and remote work opportunities has allowed pediatric radiology groups to recruit and retain in the setting of a national and international shortage of pediatric radiologists. The necessity of off-site radiologists from an operational perspective should be thoughtfully balanced against maintaining visibility in decision-making spheres both within and outside of radiology, particularly as the role of radiologists is being challenged by proponents of artificial intelligence. Problems that may arise due to a hybrid and remote model include interpersonal friction due to real or perc…

Neurocognitive Mechanism of Perceptual Errors in Radiologists: Results of Pilot Studies.

BACKGROUND: The most prevalent type of radiologist error is failing to detect abnormalities on images, the so-called "perceptual error." The prevalence of this type of false-negative (FN) error remains essentially unchanged since it was first described in 1949. Reducing this error rate would be highly beneficial for patients who often depend on radiological observations for a timely diagnosis. PURPOSE: To identify a potential neurocognitive mechanism contributing to radiologists' perceptual errors, in order to inform intervention strategies to reduce such errors in practice. These experiments…

Peritoneal Dialysis Catheter Complications after Insertion by Surgeons, Radiologists, or Nephrologists.

SIGNIFICANCE STATEMENT: The Advancing American Kidney Health Initiative aims to increase rates of utilization of peritoneal dialysis (PD) in the United States. One of the first steps to PD is successful catheter placement, which can be performed by surgeons, interventional radiologists, or nephrologists. We examined the association between operator subspecialty and risk of needing a follow-up procedure in the first 90 days after initial PD catheter implantation. Overall, we found that 15.5% of catheters required revision, removal, or a second catheter placement within 90 days. The odds of requ…

Popliteal Artery-Related Pathologies in Athletes-A Primer for Musculoskeletal Radiologists.

Vascular complications in athletes are common and mimic musculoskeletal injuries such as muscle sprains, fractures, and cartilage abnormalities. They include traumatic vascular injuries and more subtle pathologies like entrapment syndromes, pseudoaneurysms, arterial occlusions, and venous thrombosis. Such vascular complications may be occult on imaging and can be difficult for a musculoskeletal radiologist to diagnose, resulting in a lack of timely diagnosis and potentially limb-threatening consequences. Although the final diagnosis may require multidisciplinary input from orthopaedic, sports

Imaging Primer on Chimeric Antigen Receptor T-Cell Therapy for Radiologists.

Chimeric antigen receptor (CAR) T-cell therapy is a recently approved breakthrough treatment that has become a new paradigm in treatment of recurrent or refractory B-cell lymphomas and pediatric or adult acute lymphoid leukemia. CAR T cells are a type of cellular immunotherapy that artificially enhances T cells to boost eradication of malignancy through activation of the native immune system. The CAR construct is a synthetically created functional cell receptor grafted onto previously harvested patient T cells, which bind to preselected tumor-associated antigens and thereby activate host immun

Thromboelastography: a review for radiologists and implications on periprocedural bleeding risk.

Thromboelastography (TEG) and rotational thromboelastometry are emerging technologies that are gaining increasing acceptance in the medical field to evaluate the coagulation status of patients on an individual level by assessing dynamic clot formation. TEG has been proven to reduce blood product use as well as improve patient outcomes in a variety of medical settings, including trauma and surgery due to the expediated nature of the test as well as the ability to determine specific deficiencies present in whole blood that are otherwise undetectable with traditional coagulation studies.
