Fundamentals of dual-energy computed tomography and its emerging applications in bladder cancer [PDF]
Nowadays, computed tomography urography and multiparametric magnetic resonance are the most often used imaging techniques in patients with bladder cancer; however, dual-energy computed tomography is making its way into the oncological field.

Traumatic bone marrow lesions in dual-energy computed tomography
Traumatic bone marrow lesions (TBMLs) are considered to represent a range of concealed bone injuries, including haemorrhage, infarction, and localised oedema caused by trabecular microfracture occurring in the cancellous bone.

Diagnosis of Pulmonary Embolism in Unenhanced Dual Energy CT Using an Electron Density Image
Dual-energy computed tomography (CT) is a promising tool, providing both anatomical information and material properties. Using spectral information such as iodine mapping and virtual monoenergetic reconstruction, dual-energy CT showed added value over ...

Computed tomography-osteoabsorptiometry for assessing the density distribution of subchondral bone as a measure of long-term mechanical adaptation in individual joints [PDF]
To estimate subchondral mineralisation patterns which represent the long-term loading history of individual joints, a method has been developed employing computed tomography (CT) which permits repeated examination of living joints.

Role of peripheral quantitative computed tomography in identifying disuse osteoporosis in paraplegia [PDF]
Objective: Disuse osteoporosis is a major long-term health consequence of spinal cord injury (SCI) that still needs to be addressed. Its management in SCI should begin with accurate diagnosis, followed by targeted treatments in the most vulnerable ...
