Slipping Rib Syndrome (SRS) is a condition that affects adolescents and young adults. Dynamic Ultrasound imaging has a potential and likely significant role; however, limited data exists describing the protocol and techniques available for evaluating SRS. It is the intent of this study to describe the development of an effective and reproducible protocol for dynamic imaging in patients with SRS. Read More

To compare image quality ratings between 3D gradient echo mDIXON (GRE) vs. 2D turbo-spin-echo mDIXON (TSE) in pediatric patients with osteomyelitis. Read More

The objective of this work was to determine whether a 3D gradient echo-based mDIXON T1-weighted sequence can replace a TSE-based mDIXON sequence in the evaluation of bone and musculoskeletal soft tissue lesions. Read More

Radiologists have classically been taught the imaging findings of skeletal “Don’t touch lesions” on radiographs. The radiologist's goal is to best characterize these boney lesions and avoid tissue biopsy, especially since some bone lesions are misleading when viewed histologically, with nonaggressive lesions appearing aggressive. Many of these classical “Don’t touch lesions” are now being further evaluated with contrast enhanced magnetic resonance imaging (MRI). MRI findings of these radiographically classical lesions are not as well understood by radiologists with less MRI experience. We will provide an education exhibit to display MRI and corresponding radiographic appearances of characteristic “Don’t touch lesions”. Read More

3D mDIXON Gradient Echo (GRE) technical superiority has already been established: improved fat saturation, faster acquisition time, high spatial resolution, and volumetric data acquisition allowing for a comprehensive multiplanar and 3D post-contrast evaluation of vessels and soft tissue lesions. Vascular malformation imaging requires large field of view images that can adversely affect fat saturation, is frequently performed with a non-sedated patient resulting in motion artifact, and requires higher spatial resolution to better characterize a lesion and evaluate lesion extent. Additionally the interventional radiologists at our institution prefer 3D post-contrast imaging to assist in treatment planning. We believe that this sequence is well suited for vascular malformation MRI imaging. The primary purpose is to illustrate the clinical utility and superior image quality of the 3D mDIXON GRE sequence over more conventional mDIXON TSE sequence through a series of cases of a variety of vascular malformations in different body regions. The secondary purpose of this presentation is to validate the clinical superiority of this sequence through a blinded reviewer comparison to the more conventional mDIXON TSE sequence. Read More

Accurate tumor measurement is essential in initial assessment of solid tumors. Furthermore, it is vital when evaluating treatment response. Change in tumor size determines whether a treatment course is effective, if treatment should be prolonged, or whether a more aggressive treatment or chemotherapy drug should be administered. Currently endorsed and widely used guidelines for tumor volume measurement include response evaluation criteria in solid tumors (RECIST), a one dimensional measure (cm) of target lesions which is not routinely the longest axis; World Health Organization (WHO), a 2 dimensional measure of the long and one short tumor axis (cm2) but is not a measure of volume; and Childrens Oncology Group (COG), a 3 dimensional ‘volume’ (cm3) measurement but does not account for shape of the tumor. Pediatric oncology patients are almost exclusively cared for in major academic or community hospital settings where modern CT and MR scanners routinely produce direct or reconstructed multiplanar images. Therefore an evolution of tumor measurement, to determine tumor volume, must be forthcoming. Read More
