Episode 31: Imaging of Acute Trauma - Solid Organ Injury

Episode 31: Imaging of Acute Trauma - Solid Organ Injury

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.

Episode 30: Introduction to Imaging Acute Trauma

Episode 30: Introduction to Imaging Acute Trauma

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.

Episode 29: Imaging of Ovarian Masses

Episode 29: Imaging of Ovarian Masses

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

Episode 8: What Oncologists Look for in the Radiology Report

Episode 8: What Oncologists Look for in the Radiology Report

Dr. Lacey McIntosh discusses what Oncologists need in reports.

  1. Staging - know where to look (based on primary site but also pathology)
  2. Restaging - know what to expect (based on type of treatment - XRT, chemo, immunotherapy)
  3. Big picture - same, better, worse; critical lesions that may require treatment (impending fractures, spinal cord involvement)
  4. Chose words carefully - careful about using “progression” unless you are going to calculate that this meets RECIST criteria - consider using “increased tumor burden” instead

Episode 2: Arthritis – An approach to Hand & Wrist radiographs

Episode 2:  Arthritis – An approach to Hand & Wrist radiographs

Dr. Cerniglia presents a simple “ABCDEs” pneumonic (adapted from ABCs of Dr. Forrester’s original monograph Radiology of Joint Disease) to structure an approach to hand and wrist radiographs in patients with suspected or known arthritis:

A = Alignment
B = Bone production & density
C = Cartilage space
D = Distribution
E = Erosions
S = Soft tissues

The possible findings of each of these radiographic features are introduced.  Specific arthritis features will be discussed in more details in upcoming episodes.
