Topic: Imaging of Acute Trauma, Solid Organ Injury

Summary: In this episode, we continue a discussion of imaging acute trauma. This part emphasizes the imaging of solid organ injury. The organs discussed are the liver, spleen, kidney, pancreas, adrenal gland and gallbladder. We focus on recent changes in diagnostic criteria since 2018 and their significance in the daily diagnosis and management of trauma patients.

Summary:
In this episode, we discuss the basics of imaging acutely traumatized patients. We explain the difference between Level 1 and Level 2 trauma centers. We discuss the idea of trauma activation in the emergency room, using the local UMass experience as an example. We describe the diagnostic evaluation process in the trauma bay. Finally, we discuss the modern imaging protocol, again using our local experience as an example.

Classifying and categorizing ovarian masses can feel like a daunting task for radiology trainees. In this episode Dr. Alan Goldstein will discuss with us his approach to these lesions to help simplify the process. First, a few mimics and pitfalls will be presented. Then Dr. Goldstein will break down the three basic types of ovarian tumors with an emphasis on imaging features:
1. First, make sure the mass is truly ovarian in origin
(A) Appendiceal mucocele, peritoneal inclusion cyst, hydrosalpinx, subserosal fibroid, endometrioma, metastasis
2. Then break it down
(A) Epithelial tumors (cystic with solid components)
- Benign
- Borderline
- Malignant
(B) Sex cord stromal tumors (solid with cystic components)
- Fibroma
- Other stuff
(C) Germ cells tumors (bizarre masses in young patients)
- Dermoid cyst
- Other stuff

In this episode we continue our discussion of Gadolinium-based contrast agents (GBCA) from our introduction in Ep 27. Building on previous discussions of MRI safety (Ep9 & 11) and Contrast and Adverse Reactions from Ep 5 & 6, this episode will review specific considerations of gadolinium use in pregnancy and breast feeding. We also explore the non-acute adverse reactions of NSF and GDD.

This is part two of the two-part series on the basics of GBCA.

In this episode we discuss Gadolinium-based contrast agents (GBCA) or media (GBCM). Building on previous discussions of MRI safety (Ep9 & 11) and Contrast and Adverse Reactions from Ep 5 & 6, this episode will introduce MRI contrast agents (GBCA or GBCM), their make-up, categories and general safety profiles. m including some of the inherent safety issues that arise from them; the concept of safety zones and its importance; examples of unique safety issues in MRI, and the screening process. Summary of some common GBCA and their trade names includes:
Gadoteridol (ProHance) - Macrocyclic - Nonionic
Gadobutrol (Gadavist) - Macrocyclic - Nonionic
Gadoterate (Dotarem) - Macrocyclic - Ionic
Gadodiamide (Omniscan) - Linear - Nonionic
Gadoversetamide (Optimark) - Linear - Nonionic
Gadobenate (MultiHance) - Linear - Ionic
Gadopentetate dimeglumine (Magnevist) - Linear - Ionic

This is part one of a two-part series on the basics of GBCA.
