We see many patients who have had an ultrasound scan which identifies a “lesion” which is probably a haemangioma, but many radiographers (non doctor ultrasonographers) and even radiologists (medically qualified clinicians who undertake ultrasonography) will sit on the fence and be reluctant to say “this is a haemangioma”, mainly because it is hard to be certain. They are 98% certain but not certain. This makes the patient and the GP worried that they may be missing something. In this instance the best test is an MRI scan of the liver. An MRI of the liver generally takes about 30 minutes. It is noisy since the scanner makes a loud noise, and most units provide headphones and horrible piped music (you may like the music, tastes vary!). If you suffer from claustrophobia you may find such a scan difficult, but some units have open scanners which make it easier. If you undertake this privately is needs to be done with contrast, and can be quite expensive (between £500 to £1200 at a guess).
