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. 

An example of artificial intelligence (AI) automated detection of a intracranial hemorrhage (ICH) in. a CT scan used to send alerts to the stroke acute care team before a radiologist even sees the exam. Example shown by TeraRecon at RSNA 2022.

FDA has now cleared more than 500 healthcare AI algorithms

More than 500 clinical AI algorithms have now been cleared by the FDA, with the majority just in the past couple years.

An example of an FDA cleared radiology AI algorithm to automatically take a cardiac CT scan and identify, contour and quantify soft plaque in the coronary arteries. The Cleerly software then generates an automated report with images, measurements and a risk assessment for the patient. This type of quantification is too time consuming and complex for human readers to bother with, but AI assisted reports like this may become a new normal over the next decade. Example from Cleerly Imaging at SCCT 2022.

Legal considerations for artificial intelligence in radiology and cardiology

There are now more than 520 FDA-cleared AI algorithms and the majority are for radiology and cardiology, raising the question of who is liable if the AI gets something wrong.

FDA grants passage to autonomous, biology-guided radiotherapy

A therapeutic oncology company has been cleared to market a cancer treatment that that turns a tumor’s own biology into a self-signaling target for radiation therapy.

Brent Savoie, MD, JD, vice chair for radiology informatics, section chief of cardiovascular imaging, Vanderbilt University, explains who will get sued when there is a misdiagnosis due to artificial intelligence (AI).

FDA greenlights ultrasound MSK software with AI

Clarius Mobile Health of Vancouver, B.C., has won FDA approval to market an AI model that works with the company’s handheld point-of-care ultrasound devices to identify and measure tendons of the foot, ankle and knee.

COVID in pregnant women manifests by variant in developing offspring: MRI study

Prenatal MRI is adept at revealing potentially damaging placental lesions affecting fetuses whose mothers were infected with COVID-19 while carrying.

Portable orthopedic tomosynthesis cleared for U.S. sales

The FDA has cleared U.K.-based Adaptix to market a 3D X-ray system that, according to the company, images hands, feet and elbows “at a fraction of the radiation dose and per-study cost of traditional CT.”

Telemammography

4 key trends in breast imaging

These trends include growth in 3D mammography, supplemental imaging for women with dense breasts and in the role of artificial intelligence.

The patient, who was being cared for in the ICU, was not accompanied or monitored by nursing staff during his exam, despite being sedated.

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
