Acute mesenteric ischemia (AMI) is a true surgical emergency and a rare life-threatening condition, accounting for 0.01% of hospital admissions, with extremely high mortality rates (up to 69%). Poor outcomes remain prevalent despite advances in both diagnostic and treatment options over the last two decades

Early diagnosis and management are particularly important given that the highest incidence of AMI occurs in the elderly population, who often have multiple comorbidities leading to a worse prognosis. Biphasic contrast enhanced multidetector computed tomography (MDCT) images have become the mainstay and standard of care for investigation and timely diagnosis of AMI.

As such, the importance of recognizing imaging features of AMI and timely communication of findings with the referring physicians is of utmost importance for diagnostic radiologists and always a worthwhile topic for review. We have therefore endeavored to provide a brief summary of the presentation of AMI, its causes, relevant anatomy, and most importantly, illustrated review of CT findings that delineate ischemic changes of the bowel and mesentery.

Ultrasound (US) is often the initial imaging modality for evaluation of renal diseases. Non-enhanced US faces limitations in the assessment of focal renal masses and complex cysts. Contrast-enhanced ultrasound (CEUS) on the kidneys can overcome these shortcomings.

There are several advantages of CEUS over contrast-enhanced CT or contrast-enhanced MRI. These include the fact that the narrow US beam allows for improved visualization of vascularity in small structures such as septations or small mural nodules; high temporal resolution with real time assessment of vascularity; lack of radiation; and no renal impairment.

Excluding inflammatory masses, vascular abnormalities and pseudotumors, most solid enhancing renal masses are malignant. Complicated cystic lesions with enhancing soft tissue components, excluding the actual cyst wall, are malignant. Using enhancement pattern, renal masses can be characterized with high sensitivity and specificity

Pregnancy associated breast cancer (PABC) is a subset of breast cancer that is typically diagnosed at more advanced stages and carries a worse prognosis. The physiological breast changes that occur during pregnancy and lactation can often make clinical and radiological evaluation difficult.

Ultrasound is the primary imaging modality in the evaluation of pregnancy associated breast lesions with high sensitivity and lack of radiation. Mammography is generally considered safe during pregnancy and lactation and may also be used to assess for PABC. Dynamic contrast enhanced breast MRI is not recommended during pregnancy; however, it may safely be performed in lactating women to evaluate extent of disease or for high risk screening.

This article reviews appropriate imaging evaluation of the pregnant or lactating woman, and showcases the imaging features of benign and malignant lesions occurring during pregnancy and lactation. Many benign lesions, including fibroadenoma and lactating adenoma, can mimic malignancy. New or growing solid masses occurring during pregnancy and lactation should be further evaluated with imaging and biopsy, to avoid a delay in a potential cancer diagnosis.

The rapid spread of the new coronavirus disease (COVID-19) identified toward the end of 2019 significantly impacted everyone in China, and all over the world. Head and neck (HN) cancers are a common malignant tumor type in China, with chemoradiation the standard of care for locally advanced disease. However, the COVID-19 epidemic interrupted the routine diagnosis and treatment of all cancers, including HN cancers, which can progress quickly if treatment is significantly delayed. Cancer patient care at the epicenter of COVID-19 was particularly challenged. Based on the management experience of patients with HN cancer during the outbreak of COVID-19 at a cancer institute in Wuhan, the authors summarize management strategies of patients with HN cancer to provide reference for health care providers facing similar challenges.

Many acute infectious conditions of the face and neck resulting from common sources, such as pharyngitis, dental infection, and penetrating trauma, are evaluated in the emergency department. The clinical features of these conditions overlap, and clinical evaluation is often insufficient to localize or determine the extent of infection within the deep spaces of the neck.

This article showcases the classic imaging features and locations of a variety of acute face and neck infections encountered in the emergency department. In addition, the imaging findings of potentially life-threatening complications, such as mediastinitis resulting from retropharyngeal abscess and septic pulmonary emboli resulting from Lemierre syndrome, are described.

In the emergency setting, the radiologist’s ability to correctly identify and categorize acute face and neck infections and their complications is paramount to direct appropriate surgical and medical management.

Brachial plexus disorders are a diagnostic challenge due to the complex anatomy and nonspecific symptomatology. MRI remains the best modality for assessing the brachial plexus (BP), due to its superior soft-tissue contrast compared to CT or ultrasound. Traumatic lesions are the most common cause of BP dysfunction, closely followed by neoplastic infiltration. Infection, inflammation and iatrogenic causes are less common.

This review article will provide an overview of anatomy and practical, up-to-date BP imaging techniques for general radiologists, followed by a step-wise discussion of common pathology. Clinically relevant advances such as dynamic tho-racic outlet MRI will also be discussed.
