Objective: The majority of people in the world lack basic access to breast diagnostic imaging resulting in delay to diagnosis of breast cancer. In this study, we tested a volume sweep imaging (VSI) ultrasound protocol for evaluation of palpable breast lumps that can be performed by operators after minimal training without prior ultrasound experience as a means to increase accessibility to breast ultrasound.
Methods: Medical students without prior ultrasound experience were trained for less than 2 hours on the VSI breast ultrasound protocol.
Inflammatory breast cancer (IBC) is a rare variety of breast cancer accounting for two percent of breast cancer diagnoses in the United States. It is characterized by peau d'orange, breast edema and erythema on physical examination and dermal lymphatic invasion by tumor emboli on histological examination. Micrometastases to lymphatics and bone marrow at the time of diagnosis and angiogenic properties of IBC explain the high propensity of this cancer to relapse and metastasize, its aggressiveness and poor prognosis.

Neuroendocrine tumors (NETs) are a relatively rare entity; however, the incidence and prevalence of these tumors are increasing, likely attributed to improved diagnostic accuracy. The diagnosis of suspected NETs is facilitated by clinical symptoms, laboratory test abnormalities such as elevated chromogranin-A, and other diagnostic modalities such as the use of computed tomography scans, magnetic resonance imaging scans, positron emission tomography (PET) scans, and biopsy. The expression of high levels of somatostatin receptors in NETs enables the use of a specialized PET scan using the radiolabeled somatostatin analogues 68Ga-DOTATATE.

- - Craniotomy and craniectomy are emergency neurosurgical procedures used to treat conditions like trauma and cancer, making it crucial for emergency radiologists to recognize normal and abnormal imaging findings in these patients.
- - Understanding postoperative CT and MRI appearances helps avoid misinterpretations and delays in treatment, as familiarity with common complications is essential.
- - Key complications to be aware of include hemorrhage, infections, and specific issues like extracranial herniation and trephine syndrome related to craniectomies.
The anteroposterior (AP) portable chest radiograph is routinely performed to evaluate cardiopulmonary status, however heart size can be misrepresented by inherent technical factors. Our aim was to determine diagnostic accuracy of cardiothoracic ratio (CTR) on AP chest radiographs relative to echocardiography, as well as relative to axial computed tomography (CT) and frontal CT scout images in predicting cardiac chamber enlargement. 200 subjects with both chest CT and AP chest radiograph within 1 month were retrospectively identified.

Methods: Medical records of patients who underwent RPN for a single renal mass in our center from 2006 to 2013 were reviewed. Patients were divided in two groups: those who had history of PAS and those without history of PAS.
