Artificial Intelligence in Cancer Care: Legal and Regulatory Dimensions.

Considering that artificial intelligence (AI) technologies have the potential to change cancer care, this article discusses the AI features of which oncologist should most be aware.

Osmotic Demyelination Syndrome Revisited: Review With Neuroimaging.

Osmotic demyelination syndrome (ODS) is a general term that has become commonplace in the practice of medicine, encompassing both central pontine myelinolysis and extrapontine myelinolysis. Historically ODS arises as a serious complication of rapid correction of hyponatremia, yet its manifestations seem to be influenced by a multifactorial process. Further understanding of this rare demyelinating disease has elucidated the significant role of other electrolyte disturbances and the presence of chronic comorbidities as disease risk factors.

Radiology Case of the Month: Intussusception in Adults: Is There a Lead Point?

A 36-year-old woman presents to the emergency department with a 4-day history of progressive lower abdominal pain accompanied by nausea.

A Review of Supplemental Screening Ultrasound for Breast Cancer: Certain Populations of Women with Dense Breast Tissue May Benefit.

Breast density has been shown to be a strong, independent risk factor for breast cancer. Unfortunately, mammography is less accurate on dense breast tissue compared to fattier breast tissue. Multiple studies suggest a solution to this by demonstrating the ability of supplemental screening ultrasound to detect additional malignant lesions in women with dense breast tissue but negative mammography.

Radiology Case of the Month:Diagnosis and Treatment of an Acquired Uterine Arteriovenous Malformation in a 26-Year-Old Woman presenting with Vaginal Bleeding.

Arteriovenous malformations (AVMs) are a rare source of potentially life-threatening uterine bleeding, and should be suspected in patients presenting with metromenorrhagia. Histologically, AVMs are characterized as having both arterial and venous tissues without an intervening capillary network.1 The etiology may be either congenital or acquired secondary to prior uterine surgery or uterine malignancy.

Sarcoidosis of the thyroid gland and spinal canal: unique localizations.

Sarcoid involvement of the thyroid gland and spinal canal are rare individual manifestations of sarcoidosis. In this article, we will describe two concurrent cases of spinal canal and thyroid sarcoid involvement. Diagnostic criteria usually include histologic identification of a non-caseating granuloma, supportive laboratory or imaging tests or both, and a compatible clinical course.

A comparison of clinical and pathologic assessments for the prediction of occult nipple involvement in nipple-sparing mastectomies.

Background: Nipple-sparing mastectomy (NSM) for both risk reduction and cancer is increasing. In the cancer setting, most studies suggest the use of both clinical and intraoperative biopsy criteria in patient selection. This study examines the use of both biopsy and clinical criteria in women undergoing total nipple-removing mastectomy.

Radiology case of the month: two adults with intermittent abdominal pain.

Though usually thought of as a pediatric entity, intussusception may occur in adults, which account for 5% of cases. Intussusception may result from a pathologic lead point facilitating the process or may occur with no such lead point. As opposed to idiopathic predominance in children, most adult intussusception involves a lead point.

The use of multislice CT angiography preoperative study for supraclavicular artery island flap harvesting.

Background: The vascular anatomy of the supraclavicular artery island (SAI) flap has been investigated using both cadaveric anatomic dissections and angiographic studies. Accurate preoperative evaluation and localization of its vascular pedicle confirms its location, course, anatomic variation, and improves flap success. The objective of this report is to demonstrate the utility of multislice computed tomography (CT) angiography for confirming the presence of the vascular pedicle of the SAI flap when planning head and neck reconstruction.

Color Doppler sonography of endometrial masses.

Objective: To correlate the color Doppler sonographic features of endometrial masses with histologic characteristics and microvessel density.

Methods: We performed a retrospective analysis of 10 postmenopausal and 5 premenopausal women with abnormal bleeding who had color Doppler sonography and histologic studies of endometrial masses.

Results: Endometrial masses that contained multiple branches on color Doppler sonography were more likely carcinomas, even though both polyps and carcinomas were vascular on color Doppler sonography and their microvessel densities were similar.
