“…As on MRI, secondary signs, such as buckling of the posterior cruciate ligament, were also useful in their diagnosis. In this study, multidetector CT showed a low sensitivity for other softtissue injuries at the knee; however, its high specificity indicated that apparent posterior cruciate ligament, meniscal, and collateral ligament tears can reliably be treated as true-positive findings [15].…”

“…In a study by Heffernan et al [15], 64-channel multidetector CT showed 87.5% to 100% sensitivity and 100% specificity for detection of the ACL tears. As on MRI, secondary signs, such as buckling of the posterior cruciate ligament, were also useful in their diagnosis.…”

“…With negative radiographs, CT may be performed as the next imaging study for the evaluation of suspected radiographically occult knee fractures [12] and bone marrow contusions [16][17][18]. CT may diagnose or predict ligamentous injuries [14,15,50,51] and predict meniscal [15,50,51] injuries. However, MRI is superior to CT in evaluation of bone marrow lesions [27][28][29] and meniscal [21,26] and ligamentous [21,[31][32][33][34] injuries, and may be subsequently performed as clinically indicated.…”

“…Next study CT Knee. In patients with radiographic diagnosis of the tibial plateau fracture, CT is frequently performed for further classification and characterization of the fracture severity [12,52] and may predict or diagnose ligamentous injuries [13][14][15]50,51] and predict meniscal injuries [15,50]. A study by Spiro et al [50] found that the amount of articular surface depression on CT is a predictor of meniscal and ligamentous injuries and can suggest when an MRI is indicated to confirm or exclude meniscal and ligamentous injuries [50].…”

Acute trauma to the knee is a common presentation seen in the emergency department. After a routine clinical examination, imaging is frequently performed to facilitate the diagnosis and almost always starts with radiographs. If clinically indicated, advanced cross-sectional imaging may then be performed for further evaluation. CT is often performed for preoperative planning of the complex tibial plateau and distal femur fractures. Currently, MRI is the study of choice for evaluation of bone marrow, internal derangements, and other soft-tissue injuries about the knee joint. In patients with knee dislocations, MR angiography may be performed simultaneously with MRI for evaluation of internal derangements and vascular injuries with less morbidity compared to conventional angiography.

“…36 In patients with tibial plateau fractures, 50% have concomitant soft tissue injury, up to 60 to 70% have ligament tears, and 50 to 80% can have meniscal tears. 34,53 MRI is usually not available in the acute setting and can be limited in this context due to pain and image acquisition time. DECT therefore has the potential to detect the disruption of ligaments and tendons at an earlier stage, allowing for more expedient diagnosis and management of knee injuries (►Fig.…”

Dual-energy computed tomography (DECT) has the potential to detect musculoskeletal pathology with greater sensitivity than conventional CT alone at no additional radiation dose to the patient. It therefore has the potential to reduce the need for further diagnostic imaging or procedures (e.g., joint aspirations in the case of gout or magnetic resonance imaging to confirm undisplaced fractures).DECT is a well-established technique for the detection of gout arthropathy. Multiple newer applications have shown clinical potential including bone marrow edema detection and metal artifact reduction. Collagen analysis, bone marrow lesion detection, and iodine mapping in CT arthrography are areas of possible future application and development.This article outlines 10 tips on the use of DECT imaging of the musculoskeletal system, explaining the technique and indications with practical suggestions to help guide the radiologist.
