“…Exact measurement of the alpha angle can be demanding in both CT and MRI. Yan et al compared manually measured alpha angles in CT and MRI, reporting a 95% CI up to 10° with an ICC between 0.60 and 0.78 [ 15 ]. Furthermore, they showed that agreement between CT and MRI depended on the underlying deformity, observing greater discrepancies for alpha angles in Cam deformities and acetabular parameters in dysplasia.…”

Objective This study aimed at investigating the agreement between predefined quantitative parameters of hip morphology derived from magnetic resonance imaging (MRI) and virtual range of motion (ROM) analysis using computed tomography (CT) as standard of reference. Methods Twenty patients (13 females, 7 males, 16-59 years) with hip deformities underwent MRI prior to surgery. Clockwise alpha angle, femoral head and neck diameter, collum caput diaphysis angle, femoral torsion, center-edge angles, acetabular coverage of the femoral head, sourcil angle, and acetabular anteversion were measured. Additionally, tern single and combined movements were simulated using a motion analysis program. The MRI findings were compared with the corresponding results obtained by CT. Correlation of MRI with CT was assessed using different statistical methods (intraclass correlation coefficient, Bland-Altmann plot, two one-sided t test), and linear regression analysis was performed. ResultsThe results showed near-perfect intraclass correlation coefficients (ICCs) for anteversion (0.95), acetabular sector angles (0.98-0.99), sourcil angle (0.95), and acetabular coverage (anterior 0.96, posterior 0.99). Intermethod correlation for femoral parameters showed almost perfect agreement except for the alpha angle (0.73-0.97). No significant proportional bias was detected for traditional acetabular and femoral parameters. ROM analysis was performed for 370 movements in 37 hips. For 78.4% (290/370) of the movements analysed, neither CT nor MRI detected impingement across the physiological ROM. For 18.6% (69/370) of the movements, impingement was detected by both CT and MRI, while 2.2% (8/370) of the movements with impingement in CT showed no impingement in MRI, and 0.8% (3/370) of the movements with impingement in MRI had no corresponding result in CT. Conclusion Finally, it was concluded that MRI-based assessment of hip morphology and virtual ROM analysis is feasible and can be performed with good intermethod agreement in comparison to the gold standard (CT). Therefore, MRI appears to be substantially equivalent to CT for use in virtual ROM analysis and so may reasonably be used in place of CT for this purpose.

“…[17][18][19] Helical CT and 3D imaging should be preferred for evaluation once the patient has reached walking age when ossification of femoral head becomes prominent. [20][21][22] Multiplanar sagittal and coronal images should be added after CT sections in older patients with DDH, as well as 3D reconstructions that can better illustrate the coxofemoral joint with respect to all bone components and articular connections than classic axial CT sections.…”

E xamination, early diagnosis, follow-up, and treatment of infants at risk for developmental dysplasia of the hip (DDH) remains an orthopedic problem with vital importance both in our country and the world.Developmental dysplasia of the hip (DDH) is still one of the biggest orthopedic problems in the world. Global poverty and refugee crises have led to it becoming a greater issue even in developed nations. Early diagnosis and effective treatment of DDH are required to prevent the possibility of arthrosis, limb shortening, pelvic asymmetry, and vertebral scoliosis. In late cases, surgery is the only choice for correction. Direct radiography has been used for many years and continues to have an important role, though ultrasonography is the primary source for early postnatal screening. Although magnetic resonance imaging (MRI) has become an important modality to provide sectional imaging in many cases, in late-period dysplasia, computed tomography (CT) and three-dimensional (3D) CT are preferred because it can more effectively demonstrate the cortical bony structures. The aim of this review was to demonstrate the effectiveness of 3D CT and multiplanar reconstruction based on previous studies.

“…Thus isotropic 3D MRI can serve as a one-stop shop for hip evaluation. 10 Apart from the routinely used approach of variable echo time sampling and flip angle evolutions with 3D imaging, several recent developments have reduced the imaging time to < 5 to 6 minutes on a 3-T scanner and < 7 minutes on a 1.5-T scanner. These include accelerated 3D MRI with the controlled aliasing in parallel imaging results in higher acceleration (CAIPIRINHA) technique (Siemens, Erlangen, Germany) and compressed SENSE (sensitivity encoding; Phillips, Amsterdam, Netherlands).…”

Magnetic resonance imaging (MRI) is a common choice among various imaging modalities for the evaluation of hip conditions. Conventional MRI with two-dimensional acquisitions requires a significant amount of time and is limited by partial-volume artifacts and suboptimal fluid-to-cartilage contrast. Recent hardware and software advances have resulted in development of novel isotropic three-dimensional (3D) single-acquisition protocols that cover the volume of the entire hip and can be reconstructed in arbitrary planes for submillimeter assessment of bony and labro-cartilaginous structures in their planes of orientation. This technique facilitates superior identification of small labral tears and other hip lesions with better correlations with arthroscopy. In this review, we discuss technical details related to 3D MRI of the hip, its advantages, and its role in commonly encountered painful conditions that can be evaluated with great precision using this technology. The entities described are femoroacetabular impingement with acetabular labral tears, acetabular dysplasia, avascular necrosis, regional tendinopathies and tendon tears, bursitis, and other conditions.

Does 3DMR provide equivalent information as 3DCT for the pre-operative evaluation of adult Hip pain conditions of femoroacetabular impingement and Hip dysplasia?

Abstract: 3DMR has good potential to replace 3DCT and serve as a one-stop modality for bone and soft tissue characterizations in the pre-operative evaluation of FAI and HD.
