QIBA guidance: Computed tomography imaging for COVID-19 quantitative imaging applications
As the COVID-19 pandemic impacts global populations, computed tomography (CT) lung imaging is being used in many countries to help manage patient care as well as to rapidly identify potentially useful quantitative COVID-19 CT imaging biomarkers. Quantitative COVID-19 CT imaging applications, typically based on computer vision modeling and artificial intelligence algorithms, include the potential for better methods to assess COVID-19 extent and severity, assist with differential diagnosis of COVID-19 versus other respiratory conditions, and predict disease trajectory.

Systemic diseases affecting the breast: Imaging, diagnosis, and management
Various systemic diseases of benign or malignant etiologies can clinically manifest in the breast. Some imaging findings of breast lesions can be pathognomonic for a given condition, while others are non-specific, mimicking primary breast carcinoma and requiring tissue biopsy for definitive diagnosis. In addition to obtaining a detailed clinical history, radiologists should be familiar with the diverse clinical and imaging characteristics of these conditions to help exclude primary breast cancer and avoid unnecessary interventions.

Spilled stones following pyelolithotomy: An unusual mimic of peritoneal carcinomatosis
While spillage of intraperitoneal gallstones has been reported frequently in the literature, spilled renal stones after urologic intervention is rare. The dropped renal stones may mimic peritoneal carcinomatosis (PC) on imaging, causing concern and potentially leading to unnecessary diagnostic workup. Additionally, these dropped stones may cause surrounding inflammation, potentially leading to the formation of adhesions or an intra-abdominal abscess. Calcifications along the peritoneal lining are generally interpreted as peritoneal carcinomatosis until proven otherwise. (Source: Clinical Imaging)

Thymic masses and mimics in adults: review of common and uncommon pathologies
The thymus is a primary lymphoid organ that plays a key role in immune system development. Normally, it is located in the anterior mediastinum and changes tissue composition with progressive fatty involution with age. The spectrum of pathological processes involving the thymus includes enlargement, tumour development, and cystic change. In addition, other local pathology can mimic thymic disease. Differentiating these entities can be challenging; however, recognizing key features on imaging is essential to appropriately guide further investigation and therapy. (Source: Clinical Imaging)

Multimodality imaging and treatment strategy for malignant scalp neoplasms in adults
Malignant scalp masses deserve much attention as they have the potential to destroy local structures, recur and metastasize to distant organs. Moreover, malignant scalp lesions are known to be more aggressive in behavior than their counterparts elsewhere in the body. Multimodality imaging is essential in narrowing the differential diagnoses of scalp masses, as well as in differentiating benign from malignant masses. Furthermore, imaging is important in (1) evaluating the extent of tumor invasion in the scalp, (2) staging the disease, (3) guiding surgical biopsy and/or resection of the tumor, (4) preoperative planning and p...
