Which test is more advised to diagnose chest cyst and lesions but not lung lesions ? Is it Chest Ultrasound or Chest MRI or Chest X-ray ? Which test from the above tests gives a detailed picture and report of the chest cysts and lesions ? I am also attaching my MRI report for your perusal and comments please. Why do radiologists write the word "sizeable" or "size significant" in MRI or CT scans ? While capturing the images of these scans, do the very very small sized cysts or lesions get skipped ? Is that the reason for writing the term "sizeable " or "size significant" ?
