Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT. 

Experts describe MRI characteristics of rare breast cancer

The new paper describes the imaging characteristics of metaplastic carcinoma of the breast and correlates the findings with clinical and histopathological characteristics/diagnoses.

Use of ultrasound to guide needles used for femoral vascular access for cath lab procedures can help reduce bleeding and vascular complications. But the Universal Trial at TCT 2022 showed no difference. Image courtesy of Sonosite

Ultrasound guidance for femoral access did not reduce bleeding or vascular complications in TCT late-breaker

The UNIVERSAL Trial, one of the largest multicenter randomized trials comparing ultrasound with fluoroscopic guidance vs. fluoroscopic guidance alone, found there was no reduction in major vascular access complications. 

Improving the diagnostic value of portable imaging: Experts propose 3 interventions

After experts from one institution evaluated 500 portable chest x-rays completed during the summer of 2021, it was revealed that 46.2% of the images obtained were problematic, requiring the imaging to be repeated. 

Ultrasound education gets a new academy

A serial entrepreneur who began her career as a sonographer has launched her third ultrasound-based business.

The approach—called GammaTile—involves placing small radiation seeds at a tumor site during surgery.

New radiation therapy treatment stalls recurrence while sparing healthy tissue in patients with brain cancer

The treatment has the potential to “extend lifespans and improve quality of life” in patients with brain cancer, according to experts at UC San Diego Health.

MRI/PSA combo cuts down on unnecessary biopsies in patients with suspected PCa

The strategy of combining the two tests improved specificity and positive predictive value in detecting clinically significant cancer compared to PSA alone.  

Long and longer: Imaging wait times in Canada

Prior to the arrival of COVID-19 in early 2020, Canadian patients waited nearly three months for an MRI and more than 11 weeks for a CT. Things have only gotten worse since then.

A study published this week in the Journal of the American College of Cardiology (JACC): Cardiovascular Imaging shows artificial intelligence (AI) algorithms can more rapidly and objectively determine calcium scores in computed tomographic (CT) and positron emission tomographic (PET) images than physicians.[1] The AI also performed well when the images were obtained from very-low-radiation CT attenuation scans. https://doi.org/10.1016/j.jcmg.2022.06.006

Artificial intelligence can objectively determine cardiac calcium scores faster than doctors
