Parallel imaging aids 3D MRA in infants
Parallel imaging has reduced acquisition time for contrast MR, making it possible to use 3D MR angiography in imaging infants with suspected congenital abnormalities.
Parallel imaging has reduced acquisition time for contrast MR, making it possible to use 3D MR angiography in imaging infants with suspected congenital abnormalities.
The new capability was demonstrated in a study of 22 infants and small children at the University of Heidelberg using time-resolved 3D FLASH MRA performed with GRAPPA using an acceleration factor of 2 on a 1.5T scanner. All studies were deemed diagnostic with no relevant motion artifacts, according to Dr. Joachim Eichorn. Small aberrant vessels including multiple aortopulmonary collateral arteries were visualized.
In related research, Dr. Jochem van den Berg at Sophia Children's Hospital in Rotterdam, the Netherlands, found perfusion imaging uncovers otherwise undetected ventricular diastolic dysfunctions including impaired relaxation and filling restrictions linked to the tetralogy of Fallot.
Dr. Giulia Russo at the University of Padua in Padova, Italy, described the value of delayed-enhancement MRI for assessing the risk of sudden death among 27 consecutive adults with repaired tetralogy of Fallot. Delayed enhancement was seen in seven of eight patients with histories of life-threatening arrhythmic events but only two of 19 without incidences of sustained ventricular tachycardia.

European Society of Breast Imaging Issues Updated Breast Cancer Screening Recommendations
April 24th 2024One of the recommendations from the European Society of Breast Imaging (EUSOBI) is annual breast MRI exams starting at 25 years of age for women deemed to be at high risk for breast cancer.
Study Reveals Benefits of Photon-Counting CT for Assessing Acute Pulmonary Embolism
April 23rd 2024In comparison to energy-integrating detector CT for the workup of suspected acute pulmonary embolism, the use of photon-counting detector CT reduced radiation dosing by 48 percent, according to newly published research.
