CT

USPSTF lung cancer screening recommendation update; Cancer screenings and COVID-19; and CT and unintentional weight loss.

Cumulative radiation dose exposure is a concern for this group.

Scans are useful in identifying causes of nearly half of patients in the emergency department who have unintentional weight loss.

The PET/CT scanner allows simultaneous whole-body imaging from top of the head to thigh.

Revised guidelines support low-dose CT screening for patients between ages 50 and 80 with 20-pack year smoking histories – a move that lowers the screening age and, potentially, incorporates more high-risk individuals.

The impacts of the pandemic have been long-lasting – what has the effect been, and what prompts patients to return.

Here's what to expect this week on Diagnostic Imaging.

An automated approach can be useful with patients who have indeterminate transthoracic echocardiograms.

Radiologists can play an active role in improving the healthcare experience for transgender patients, most of whom have had a negative imaging encounter.

More radiologists are providing CT and MRI services, but these studies still fall behind echocardiography and nuclear medicine.

Here's what to expect this week on Diagnostic Imaging.

CT Colonography & Tumor Differentiation; COVID-19 & Leukoencephalopathy; MRI, the Angiography Suite, and Acute Ischemic Stroke; Plus, DBT, African American Women, & Decreased Access

What is your diagnosis for a patient who presents with increasing size of neck and shoulder region?

Implementing a radiomics-based machine learning algorithm allows CT colonography to differentiate between benign and pre-cancerous polyps with high sensitivity and specificity.

Here's what to expect this week on Diagnostic Imaging.

Mammography "Sweet Spot" Recall Rate; MRI for Early-Stage Testicular Cancer Follow-Up; COVID-19 and Body Self-Attack; Plus, Global Radiology

New strategy can better detect any remaining malignant tissue intraoperatively, increasing surgeon confidence and decrease patient anxiety.

CT, MRI, and ultrasound images reveal the myriad of ways the virus prompts the body to attack itself – with this knowledge, radiologists can better contribute to treatment planning.

Using radiomics to assess impact of unconventional risk factors, including cocaine use and HIV infection, potentially introduces a “brave new world” of precision phenotyping in CAD.

Using MRI – rather than CT – for post-surgical monitoring can effectively detect cancer relapse without exposing men to unnecessary radiation.

Can you diagnose this patient with unexplained weight loss?

These radiopharmaceuticals are less expensive, and they offer longer half-lives.

Not all radiologists adhere to practice guidelines that direct providers how to respond to the presence of pulmonary nodules.

Can you diagnose this patient with a deformed chest wall and chronic history of gradual shortness of breath?
