High signal in edema, such as in more severe stress fracture. [11] Shin splints pictured: Fluid-attenuated inversion recovery: FLAIR: Fluid suppression by setting an inversion time that nulls fluids: High signal in lacunar infarction, multiple sclerosis (MS) plaques, subarachnoid haemorrhage and meningitis (pictured). [12] Double inversion ...
An MRI pulse sequence in magnetic resonance imaging (MRI) is a particular setting of pulse sequences and pulsed field gradients, resulting in a particular image appearance. [ 1 ] A multiparametric MRI is a combination of two or more sequences, and/or including other specialized MRI configurations such as spectroscopy .
Stress fractures most frequently occur in weight-bearing bones of the lower extremities, such as the tibia and fibula (bones of the lower leg), calcaneus (heel bone), metatarsal and navicular bones (bones of the foot). Less common are stress fractures to the femur, pelvis, sacrum, lumbar spine (lower back), hips, hands, and writs. Stress ...
intra articular comminuted fracture of base of first metacarpal: axial load along the metacarpal causing splitting of the proximal articular surface: Rolando's fracture at Wheeless' Textbook of Orthopaedics online Runner's fracture: Running: stress fracture of distal fibula 3–8 cm above the lateral malleolus: repeated axial stress on fibula
Nuclear medicine tests differ from most other imaging modalities in that nuclear medicine scans primarily show the physiological function of the system being investigated as opposed to traditional anatomical imaging such as CT or MRI. Nuclear medicine imaging studies are generally more organ-, tissue- or disease-specific (e.g.: lungs scan ...
The Injury Severity Score (ISS) is an established medical score to assess trauma severity. [1] [2] It correlates with mortality, morbidity and hospitalization time after trauma.
This stage appears on MRI as an isolated bone marrow edema pattern without a fracture line and is called stress reaction. Then, periosteal new bone forms and may be visible on radiography. Full cortical fractures occur if the repetitive stress continues. Only timely detection and appropriate management can interrupt this sequence. [1]
MRI is a newer technique used to diagnose spondylolysis and is favorable for a few reasons. The MRI is much more accurate than the x-ray and also does not use radiation. The MRI uses powerful magnets and radio frequencies to produce very detailed images of many different densities of tissue including bone and soft tissues. [13] [16]
