Aims and objectives
To determine the accuracy of limited protocol MRI knee comprising of sagittal PD and coronal STIR in the diagnosis of tears of medial meniscus,
ACL and PCL in cases of acute knee pain confirmed by full protocol MRI of knee joint.
Methods and materials
The cross-sectional study was conducted at Radiology department of a tertiary care hospital from Feb 2017 to Apr 2017.
A total of 233 patients of any age or gender presenting for routine MRI knee with any complaint were included through non-probability convenient sampling.
While patients with MRI claustrophobia or with any contraindication to MRI such as any metallic device or implant was excluded. MRI was performed on 1.5 Tesla or 0.4 Tesla MRI machines.
Axial and sagittal T2 weighted...
A total of 233 patients fulfilling the inclusion criteria were included in the study.
There were 56 (24%) males and 177 (76%) females.
The mean age of the patients was 35.83 ±13.01 years. Diagnostic accuracy of limited protocol MRI knee for evaluation of injuries of medial meniscus,
anterior cruciate ligament and posterior cruciate ligament was calculated by comparing it with full protocol MRI knee.
Out of 233 patients,
true positive cases for anterior cruciate ligament,...
Acute traumatic knee injuries may limit full movement of knee (6) and MRI has become a reliable tool for evaluation of internal derangement of the knee resulting from trauma (7).
This study was an attempt to study the use of sagittal proton density (PD) and coronal short tau inversion recovery (STIR) sequences together as a limited protocol for evaluation of knee trauma in a country where majority of population belong from socioeconomic status of lower or lower middle class (8).
