#1
Sandor Roth, Maja Zaninovic, Aron Roth
The present report illustrates a very rare case report of a foreign body granuloma of the foot associated with a 2-year period of a retained spongeous rubber foreign body after a penetrating injury. Because it appeared almost 2 years after the injury, the history of trauma was minimized, the foreign body had migrated from the plantar to the dorsal side of the foot, and the radiographic appearance resembled a malignant process, it was difficult to rule out the possibility of a malignant tumor. This case shows the weakness of magnetic resonance imaging in detecting spongeous rubber in the body...

Graduating physicians in all subspecialties have an increased need for competency in radiology, particularly since the use of diagnostic imaging continues to grow. To integrate the teaching of radiology with anatomy during the first year of medical school at Howard University, a novel approach was developed to overcome the limitations of resources including funding, faculty, and curricular time. The resulting program relies on self-study and peer-to-peer interactions to develop proficiency at manipulating free versions of medical image viewer software (using the DICOM standard), identifying normal anatomy in medical images, and applying critical thinking skills to understand common clinical conditions...

BACKGROUND: The Accreditation Council of Graduate Medical Education (ACGME) guidelines require residency programs to teach and evaluate residents in six overarching "core competencies" and document progress through educational milestones. In order to assess the progress of orthopaedic interns' skills in performing a history, physical exam, and documentation of the encounter for a standardized patient with spinal stenosis, a Structured Objective Clinical Examination (OSCE) was conducted for 13 orthopaedic intern residents, following a one month boot camp that included communications skills and curriculum in history and physical examination...

Bitewing radiography is still considered state-of-the-art diagnostic technology for assessing cavitation within approximal carious dental lesions, even though radiographs cannot resolve cavitated surfaces but instead are used to measure lesion depth in order to predict cavitation. Clinicians need new technologies capable of determining whether approximal carious lesions have become cavitated because not all lesions progress to cavitation. Assessing lesion cavitation from near-infrared (NIR) imaging methods holds great potential due to the high transparency of enamel in the NIR region from λ=1300-1700-nm, which allows direct visualization and quantified measurements of enamel demineralization...

BACKGROUND: Over 50% of patients who receive stereotactic body radiotherapy (SBRT) develop radiographic evidence of radiation-induced lung injury. Radiomics is an emerging approach that extracts quantitative features from image data, which may provide greater value and a better understanding of pulmonary toxicity than conventional approaches. We aimed to investigate the potential of computed tomography-based radiomics in characterizing post-SBRT lung injury. METHODS: A total of 48 diagnostic thoracic computed tomography scans (acquired prior to SBRT and at 3, 6, and 9 months post-SBRT) from 14 patients were analyzed...

OBJECTIVES: Constipation is a common diagnosis in the pediatric emergency department (ED). Children diagnosed with constipation may undergo an abdominal radiograph (AXR) as part of their diagnostic workup despite studies that suggest that an AXR in a patient suspected of being constipated is unnecessary and potentially misleading. We aimed to decrease the percentage of low-acuity patients aged between 6 months and 18 years diagnosed with constipation who undergo an AXR in our pediatric ED from 60% to 20% over 12 months...

BACKGROUND: Current assessment of spine growth for patients undergoing growth friendly surgical treatment for early-onset scoliosis (EOS) is the use of serial, 1-dimensional standard-of-care coronal vertical spine height (SoCVH) measurements. Any growth of the spine out of the coronal plane is missed by the SoCVH, which may underestimate the actual growth of the spine. This study set to validate the novel 3-dimensional true spine length (3DTSL) radiographic measurement technique for measuring growth of EOS patients...

In addition to clinical examination, forensic odontologists can use diagnostic imaging as an auxiliary method for identification. This paper reports a case where forensic odontologists from the Afrânio Peixoto Legal Medicine Institute in Rio de Janeiro (Brazil) positively identified a carbonized and partially calcined body using oral and maxillofacial imaging. The cadaver showed several metallic plates fixed with metallic screws on bones of the neurocranium and viscerocranium. Family members provided spiral computed tomography scans of the skull and a panoramic radiograph that were acquired after an accident that required surgical procedures...
