Case-Based Learning (CBL) Student Guide
In this guide What is CBL? Case-Based Learning (CBL) is an active, small-group learning environment that uses a clinical case to prompt inquiry and exploration of core clinical and scientific concepts while developing clinical reasoning skills in a structured manner. With the guidance of faculty facilitators and collaboration with peers, you’ll explore various core concepts […]

5. CT vs. MRI
When talking about CT vs. MRI, there is a lot of overlap with similar accuracies. The expertise and type of equipment your imaging partners have may determine the best test to use. However, for imaging of the central nervous system, spine, and spinal contents, MRI is superior in almost all applications. MRI is the best […]
4. Magnetic Resonance Imaging (MRI)
Magnets, computers, and ham radios MRI, like ultrasound and CT, uses sophisticated computer systems to collect and analyze data, i.e., reflected echos (think fish finder) in ultrasound and X-ray density for CT. MRI measures the mysterious values T1 and T2. T1 and T2 are values that relate to how molecules with a magnetic tendency (dipoles) […]
3. Computed Tomography (CT)
Computed Tomography (CT) is the marriage of computers and X-rays. In modern machines, a rotating gantry holds a specialized X-ray tube, which generates a highly contoured X-ray beam in opposition to a detector array surrounding the patient. The patient moves through the gantry. Gantries weigh around 6,000 kilograms and can achieve speeds of 300 milliseconds […]
2. Ultrasound
Ultrasound utilizes ultrasonic sound waves in the 2–10 MHz range generated by a handheld piezoelectric crystal, sonically coupled to the skin by gel. A computer controls the process, allowing complex modeling of the sound beam. Higher frequencies have better resolution but poorer depth penetration. Transducer selection is a compromise between the depth of the area […]
1. X-ray
Craniocaudal magnification showing malignant breast calcifications. Case courtesy of Melbourne Uni Radiology Masters, Radiopaedia.org, rID: 43928 X-rays are produced by bombarding a dense target (the anode) with high-energy (5–110 Kv) electrons, which produces a beam that radiates outward from a small point source. The beam is shaped with lead shutters. This geometry can lead to […]
Radiology
In these learning materials Introduction to Imaging Please review this material prior to class and fill out the compare/contrast matrix as best you can. There is more information than can be covered in two 50-minute sessions, so the large-group session will attempt to cover concepts that tend to be confusing. Bring your questions. Remember, this […]
Degraded Air Quality
These materials are based on the PowerPoint presentation by Anthony Gerber, MD, Division of Pulmonary and Critical Care, National Jewish Hospital. What you’ll learn Discover the climate change effects of ozone, PM2.5, and other ambient respiratory irritants on respiratory diseases such as asthma, COPD, chronic lung disease, cardiovascular disease, cerebrovascular, and allergic diseases. Analyze data […]
