In the evaluation of patients with pre-arthritic hip disorders, making the correct diagnosis and identifying the underlying bone pathology is of upmost importance to achieve optimal patient outcomes. 3-dimensional imaging adds information for proper preoperative planning. CT scans have become the gold standard for this, but with the associated risk of radiation exposure to this generally younger patient cohort. To determine if 3D-MR reconstructions of the hip can be used to accurately demonstrate femoral and acetabular morphology in the setting of femoroacetabular impingement (FAI) and development dysplasia of the hip (DDH) that is comparable to CT imaging.Introduction
Purpose
To evaluate whether an ultra-low-dose CT protocol can diagnose
selected limb fractures as well as conventional CT (C-CT). We prospectively studied 40 consecutive patients with a limb
fracture in whom a CT scan was indicated. These were scanned using
an ultra-low-dose CT Reduced Effective Dose Using Computed Tomography
In Orthopaedic Injury (REDUCTION) protocol. Studies from 16 selected
cases were compared with 16 C-CT scans matched for age, gender and
type of fracture. Studies were assessed for diagnosis and image
quality. Descriptive and reliability statistics were calculated.
The total effective radiation dose for each scanned site was compared.Aims
