We have had a number of false positive studies in the lateral wall on our sestamibi SPECT studies. We are using a single head camera, patient supine and left arm up positioning. Floods and bars look good. Any ideas why this could be happening?

Greetings For my friends in Diagnostic Radiology considering fellowships... I strongly recommend and advocate considering Cleveland Clinic (CCF) for your cardiac and thoracic imaging fellowships. OVERALL STRENGTHS: Dedicated and world renown staff to each sub-subspecialty, combining an...

Outside of Congenital, Transplant / Mechanical Assist device / Heart failure, I've noticed that there are a lot of senior fellows/residents taking 6 months to a year for further super fellowship training following graduation. Was interested to see what everyone's opinions were on the different...

Stroke volume is the amount of blood ejected by the ventricle in one beat and is determined by ventricular preload, afterload, and contractility. How can stroke volume be decreased? a) Increase heart rate b) Increase ventricular contraction c) Decrease aortic pressure d) Decrease total...

Hi all, In a pressure-volume loop, if preload is increased stroke volume is increased, but it doesn't appear to increase systolic pressure at all. However, from the equation: MAP= SV x HR x TPR I would be inclined to think an increase in stroke volume would increase systolic volume. Where am...

Hey Guys, I am the founder of a company that is attempting to educate the general public about cardiac health and help them better understand their overall health. Wristbeat is changing how people approach their heart health by providing them with the tools and knowledge to understand and...

Just wondering what everyone found most useful. Are the lectures that the JCTSE sets up adequate, or is it better to grab a good thoracic book (medical management of thoracic sx...) and cardiac book (no f***in idea) and just go from there. Cheers.

Hey guys, I have something that I can't seem to find well-explained. Venous return and cardiac output curves use right atrial pressure on the X-axis. Costanzo says that it is used as a proxy for end diastolic volume but does not explain why right atrial pressure can be used instead in this...

Hello everyone , i dont know if this is a stupid question but its driving me crazy!! IF LVEDV is the volume of blood contained at LV at the end of diastole , and diastolic dysfunction = problem with filling , how is it possible for EDV to be normal in diastolic dysfunction ?? From my...
