"This book explores concepts and methods of mastering the nuances and unique diagnostic information offered by MR imaging, when applied to the head and neck. Benign or malignant processes may cause lymphadenopathy; an infected or hemorrhagic congenital mass may be detected in adulthood; serous fluid or pus may appear similar on imaging studies, are typical examples of why this region of the human body appears mysterious to many radiologists and other imaging experts. Solving these mysteries can often be accomplished by corroborative data obtained from CT or CT/PET studies, as highlighted in this product"--Provided by publisher.
