Regular CT vs HRCT

Posted by cwal @cwal, Nov 6, 2023

Perhaps someone knows an answer to this. I recently had a High Resolution chest CT on which the radiologist reported "no tree in bud" changes associated with MAC. All my previous CT scans were "regular" CT scans and reported tree in bud changes. Why would it show on a "regular " CT but not a HRCT?

Interested in more discussions like this? Go to the MAC & Bronchiectasis Support Group.

Yes, I'd love to have a new pulmonologist. However, I'm very limited on choice where I live. There are only 2 different groups and the current group I am with will not let you change to a different physician within that group. So, if I do switch to someone in the other group and they also end up being of the same temperament as my current physician then I'm back at square one if that group has the same policy. I'm am currently trying to find some "inside" info about the other group that may help my decision.

Also, as I understand it, a HRCT is the better diagnostic tool in conditions such as MAC. ??

An AFB culture from a sputum is the first test. More invasive tests would be from a traditional bronchoscopy or in rare cases, a lung biopsy. The latest test is a super dimension bronchoscopy (Electromagnetic Navigation Bronchoscopy (ENB)), which is better than both.
CT's usually confirm evidence of MAC, bronchiectasis, etc and lung damage and measures the progression of the lung damage. I've had them all. Second opinions are common, I've had 4. Explain things to your PCP, they might be able to help. Also get referred to an ID Dr.
