Cardiac imaging
"Magnetic resonance imaging" (originally called nuclear magnetic resonance imaging), an imaging methodology based on aligning the spin axis of nuclei within molecules of the object being visualized using both powerful superconducting magnets and radio frequency and detectors. Cardiology uses are growing, especially since MRI differentiates soft tissues better than CT and allows for comprehensive exams including the quantitative assessment of size, morphology, function, and tissue characteristics in one single session. Current implementations for Cardiology uses are sometimes limited by lengthy protocols, claustrophobia and contraindications based on some complex metallic implants (pacemakers, defibrillators, insulin pumps), while artificial valves and coronary stents are generally not problematic. Image quality can be reduced by the continuous movement of heart structures. There is a promising future in cardiac MRI by more efficient scans, increasing availability of scanners and more widespread knowledge about its clinical application.
Podiatry
All podiatrists may refer patients for Medicare rebatable plain x-rays of the foot, leg, knee and femur, as well as ultrasound examination of soft tissue conditions of the foot. Podiatrists may refer patients for other radiology investigations such as CT, MRI or bone scans, however Medicare rebates do not currently exist for these examinations. Similarly, podiatrists may refer patients when needed to specialist medical practitioners, or for pathology testing, however similar exclusions in the Medicare Benefits Schedule prevent rebates being available to patients for these referrals.
