INTRODUCTION TO RADIOLOGY J. MARK FULMER, MD MEDICAL DIRECTOR DARLENE G. CASS WOMEN’S IMAGING CENTER PAST PRESIDENT MEDICAL STAFF MEDICAL DIRECTOR ER IMAGING BLAH, BLAH, BLAH DALLAS, TEXAS INTRODUCTION TO RADIOLOGY J. MARK FULMER, MD 972-523-4323 [email protected] INTRODUCTION TO RADIOLOGY COME TO THE LECTURES READ THE SYLLABUS LOOK AT THE IMAGES PARTICIPATE IN THE REVIEW INTRODUCTION TO RADIOLOGY MODERN MEDICAL IMAGING IS OFTEN AT THE CENTER OF THE DIAGNOSTIC EVALUATION, CRUCIAL IN EVALUATING RESPONSE TO THERAPY, AND ESSENTIAL IN POPULATION HEALTH SCREENING. INTRODUCTION TO RADIOLOGY SHOW YOU THE TOOLBOX INTRODUCE INTERPRETATION IMPROVE ORDERING EFFICIENCY INTRODUCTION TO RADIOLOGY ANATOMIC IMAGING FUNCTIONAL IMAGING IMAGING GUIDED INTERVENTION INTRODUCTION TO RADIOLOGY RADIOGRAPHY FLUOROSCOPY ULTRASOUND COMPUTED TOMOGRAPHY MAGNETIC RESONANCE IMAGING NUCLEAR MEDICINE RADIOGRAPHY RADIOGRAPHY X-RAYS ARE PRODUCED BY CATHODE RAY TUBES. ELECTRONS ACCELARATE FROM CATHODE TO THE ANODE. IF THE TUBE ISN’T ON, THERE ARE NO X-RAYS. RADIOGRAPHY RADIOGRAPHY RADIOGRAPHY FLUOROSCOPY FLUOROSCOPY COMPUTED TOMOGRAPHY DIGITAL MAMMOGRAPHY BASIC RADIOGRAPHIC DENSITIES AIR FAT MEAT BONE METAL BASIC RADIOGRAPHIC DENSITIES MARGINS ARE MADE WHEN THE DIFFENT DENSITIES APPOSE ONE ANOTHER. IF THE DENSITIES BECOME THE SAME, THE MARGIN DISAPPEARS.
