Hello doctor,

I am taking an MRI of my aorta once a year to check for the development of dissections, aneurysms, and enlargement of my aortic root. This is because my family can have connective tissue disorder (not yet diagnosed). I just got back from my MRI, and doing this every year. I have a habit of checking my images myself.

If you could take an overall look and see if there is anything unusual. More specifically, measurement of the sinuses of Valsalva. The most pressing thing is that I saw what I think is a false lumen, but I am no radiologist and might very well be very wrong, but I would like this to be checked. I am waiting for my results to come back.



Welcome to

I am glad that you are an aware patient and getting yourself screened annually for aortic pathologies. The aortic origin, arch, and descending thoracic aorta show normal caliber lumen (attachment removed to protect patient identity). Abdominal aorta and its branches appear normal. No significant intimal thickening or plaque disease is seen. No intra-luminal filling defects seen. No sub-intimal collection or double lumen (to suggest aortic dissection) seen in the present scan.

Flow and pulsation movement-related artifacts seen within the lumen are unavoidable in dynamic MRI scans (as seen in the reference images attachments sent by you). The measurements of the aorta at sino-tubular junction and sinus are within normal limits. Impression: Essentially normal aortic study. Regarding your pulse, I would request you for an ECG as ectopic beats and low volume pulses can be missed in manual or machine count but are well appreciated on ECG could indicate underlying arrhythmia.

Hi doctor,

Thank you for your reply.

Could you send me the measurement of the Valsalva? In cm or mm, if you could? In reply to my question about the specific image where I thought I saw a lumen, what you mean to say is that this is an artifact image from my pulse? Essentially normal: What did you find that is not within the normal?



Welcome back to

The measurements are as follows: The aortic sinus of Valsalva measures approximately 33 mm. The sino-tubular junction measures approximately 30 mm. Yes, those are artifacts. Essential normal as correlation with 2D echo is recommended for cardiovascular diseases. MRI wise it is normal. Take care.
