How to optimize the Radiology protocol during the global COVID-19 epidemic: Keypoints from Sichuan Provincial People's Hospital
Currently, the COVID-19 pneumonia epidemic is spreading worldwide. Pulmonary imaging plays an important role. The pulmonary imaging (chest computed tomography and Digital radiography) are indispensable for definitive diagnosis and reexamination. It should be noted that nosocomial infection is not uncommon. Many cases including health workers are infected. This is the experience of our radiology department's protocols during the outbreak, we used this protocol to cope with the COVID-19 in Sichuan Province , besides,there is zero infection for health workers during the whole epidemic.

Imaging spectrum of NUT carcinomas
Nuclear protein of the testis (NUT) carcinoma (NC) (formerly known as NUT midline carcinoma) is an aggressive pleomorphic squamous cell carcinoma with a dismal prognosis. Primary NC tumors are commonly located in the chest or head and neck regions. Imaging plays an indispensable role in the staging, management, treatment response assessment, and surveillance of NC. Primary pulmonary NC usually presents as a large mass with lymphadenopathy and pleural involvement. Primary head and neck NC presents as a large expansile necrotic mass in the sinonasal region with locoregional destruction and occasional cervical lymph node invo...

Differences in citation counts of radiology journals between citation databases
Citation counts relate to the scientific reach and measure the impact of articles, journals, and researchers [1]. This metric is frequently used as evidence of academic advancement by faculty when applying for promitions. It is also an important metric to gauge a journal's reputation and impact [1]. The most popular databases that record and index citations include Web of Science (WoS) (Clarivate, Philadelphia, PA), Scopus (Elsevier Inc., Amsterdam, Netherlands), and Google Scholar (GS) (Alphabet Inc., Mountain View, CA).

Central nervous system and spinal cord tuberculosis: Revisiting an important disease
Tuberculosis is a worldwide pandemic. Estimated that about 25% humans are colonized by Mycobacterium tuberculosis and about 1% are believed to develop the infection in the central nervous system (CNS-TB). Given the importance of this disease and its high levels of morbidity and mortality, it is imperative that every radiologist must be reminded of the most common findings of CNS-TB as there are several related differential diagnoses for this disease.The most common form CNS-TB is tuberculous meningitis (TBM), characterized mostly by basal meningitis, but infarction, hydrocephalus and tuberculomas could be present.

The bullseye sign: A variant of the reverse halo sign in COVID-19 pneumonia
The predominant pulmonary imaging findings on chest CT in the novel 2019 coronavirus infection (COVID-19) are bilateral ground glass opacities. The reverse halo sign is uncommon. This is a report of the new “bullseye sign,” which is considered a variant of the reverse halo sign and favored to represent a focus of organizing pneumonia. The specificity of this finding is unclear, however its presence should alert radiologists to the possibility of COVID-19 infection. (Source: Clinical Imaging)

“Radioactive” fails to tell the true Curie story
The great pandemic of 2020 has exposed many of the challenges that women scientists continue to face as they balance their professional and personal responsibilities. The marriage of Pierre and Marie Curie was described by Henri Poincar é as “not just an exchange of ideas but also an exchange of energy, a sure remedy for the temporary discouragement faced by every researcher”. One of my favorite aspects of their story is the fact that Pierre initially refused the Nobel Prize awarded to him and Henri Becquerel in 1903, insistin g on his wife's work also being honored and making her the first woman to rece...

The recent COVID-19 pandemic has impacted every facet of life and placed a significant strain on healthcare resources worldwide.

In certain parts of the world, the toll on healthcare workers has been immense, and practicing outside one's traditional scope and comfort zone has become the rule rather than the exception.

A 50-year-old male presented with bilateral lower extremity plain is found to have a wedge-shape hypodense region in the hepatic quadrate lobe. The hypoenhancement was thought to be a result of systemic-portal venous shunting due to IVC obstruction, a “cold” version of the classically described hot quadrate sign. Follow-up CT confirmed the diagnosis. Venous drainage pathway for both hot and cold quadrate signs is discussed. (Source: Clinical Imaging)

Pituitary sellar spine in a pediatric patient with diabetes insipidus
A sellar spine is a midline bony spur arising from the ventral aspect of the dorsum sellae. Representing a remnant of the anterior notochord, it is often an incidental finding and thought to be of no clinical significance. However, it has recently been suggested that a potential association may exist between sellar spine and pediatric pituitary endocrinopathies, possibly caused by deformation of the developing pituitary gland by the sellar spine. To our knowledge, this is the first case report demonstrating an association between sellar spine and clinical diabetes insipidus. (Source: Clinical Imaging)

Current comments on contrast media administration in patients with renal insufficiency
Contrast media administration has been associated with complications such as nephropathy, cardiovascular morbidity, and neurovascular events, particularly in patients with renal insufficiency. This association has been questioned in recent studies. This review was performed to summarize the most current evidence on contrast induced nephropathy (CIN), contributing factors, and considerations in patients with renal insufficiency. The risk of CIN was over-estimated by the previous studies, due to a lack of control groups or presence of non-randomized control groups, which led to a selection bias. (Source: Clinical Imaging)

High-risk third trimester pregnancy with decompensated cirrhosis safely delivered following emergent preoperative interventional radiology for mitigation of variceal bleeding
Coagulopathy coupled with severe portal hypertension in the setting of cirrhosis increases the risk of mortality from variceal bleeding in pregnant women. Studies suggest transjugular intrahepatic portosystemic shunt (TIPS) creation to be a safe procedure during pregnancy in preventing variceal bleeding complications; however, it is not typically employed in severely decompensated cirrhosis.
