$Synchrotron X-ray diffraction can aid in the diagnosis of invisible traumatic brain injuries$

Synchrotron X-ray diffraction can aid in the diagnosis of invisible traumatic brain injuries

Traumatic brain injuries (TBIs) are usually diagnosed with MRI and computed tomography scans, but these techniques often miss more mild damage.

Analyzing pathological outcomes in single vs multiple architectural distortion on digital breast tomosynthesis

According to ARRS' American Journal of Roentgenology (AJR), for patients with multiple architectural distortion (AD) identified on digital breast tomosynthesis (DBT), biopsy of all areas may be warranted, given the variation of pathologic diagnoses across AD in individual patients.

AI vs. clinical reports for the detection of incidental pulmonary embolus on chest CT

According to ARRS' American Journal of Roentgenology (AJR), an AI tool for detection of incidental pulmonary embolus (iPE) on conventional contrast-enhanced chest CT examinations had high NPV and moderate PPV for detection, even finding some iPEs missed by radiologists.

New K+-sensitive dual-mode imaging probe for diagnosis of tumor malignancy

Tumor malignancy identification plays an essential role in clinical management of cancer. Currently, biopsy is the gold standard for malignancy identification in most tumor cases, it is, however, invasive that can cause great discomfort to patients, and potentially increase the risk of distant metastases due to the complex sampling process.

$Ultrasound-derived fat fraction is linked to MRI proton-density fat fraction and helps detect hepatic steatosis$

Ultrasound-derived fat fraction is linked to MRI proton-density fat fraction and helps detect hepatic steatosis

According to ARRS' American Journal of Roentgenology (AJR), ultrasound-derived fat fraction (UDFF) is strongly associated with MRI proton-density fat fraction (PDFF) and provides high sensitivity for detecting hepatic steatosis.

Etiologies of liver cancer are changing and the prognosis is mixed, study says

The primary causes of liver cancer are well known: viral (hepatitis B and C), alcohol and non-alcoholic steatohepatitis (NASH), a condition in which fat builds up in the liver, resulting in chronic inflammation and damage.

Pneumonia frequency and severity found to be lower in patients with full COVID-19 vaccination

According to ARRS' American Journal of Roentgenology (AJR), evaluating chest CT findings offers an additional approach for demonstrating the efficacy of different COVID-19 vaccines in reducing the impact of a COVID-19 diagnosis.

Ultrasound localization microscopy can image microscopic vessels and measure blood flow in the brain

To image microscopic vessels and measure blood flow in the brain, researchers use a tool called ultrasound localization microscopy. It works by using microscopic bubbles circulated through the bloodstream as a contrast agent to measure the reflection of high-frequency acoustic waves passing through the body.

Study shows potential role for MRI with DWI in surveillance protocols after pancreatic cancer resection

According to ARRS' American Journal of Roentgenology, adding diffusion-weighted MRI (DWI) to conventional MRI improves the differentiation of locally recurrent tumor and post-surgical fibrosis after pancreatic ductal adenocarcinoma (PDAC) resection, primarily due to improved sensitivity for recurrence.

Deep learning technology boosts the speed of localization photoacoustic imaging

After a lightning strike, thunder can be heard for a short period of time afterward. This is due to the fact that the surrounding material that was struck by lightning absorbs the light, and as a result of the conversion of this light into heat, the material expands and produces a sound.
