If you don’t mind scrolling through other titles that might not interest you, I’ve reviewed a number of books here that could work for you: My Recent Reviews [Memory Books] - #9 by RMBittner
I’ll second the suggestion for a number of Dominic O’Brien’s books, as well as Solomon’s Memory Palace, Dr. Lynne Kelly’s Memory Craft, Nelson Dellis’s Remember It!, and Ed Cooke’s Remember, Remember.
Because of your interest in medical memorization, you may also want to look at Alex Mullen’s website (I believe its MullenMemory.com).
