Quantifying sclerotic bone metastases with 2D ultra short TE MRI: A feasibility study

Abstract

The significant linear relationship between percentage change in T2* as derived from UTE MRI and percentage change in HU from corresponding CT studies is indirect evidence that they are measuring effects of the same process.If the relationship between T2* and electron density holds true in further studies it offers potential for MR guided radiotherapy planning as well as attenuation correction for PET/MRI.

Differential diagnosis of osteoblastic metastases from bone islands in patients with lung cancer by single-source dual-energy CT: Advantages of spectral CT imaging

“…Although diffusionweighted imaging and dynamic-enhanced T1-weighted imaging were reported to be useful for the differential diagnosis of spinal lesions [27][28][29], some contraindications and a high expense may limit a clinical use of MRI. At present, ssDECT is not suitable as a modality of first choice for the diagnosis of vertebral metastases due to the need of radiation exposure and special equipment.…”

Bony metastases: assessing response to therapy with whole-body diffusion MRI

“…Susceptibility weighted (T2*) sequences can be made sensitive to susceptibility dephasing induced by trabecular bone [ 33 ] . Recently, ultrashort echo time sequences have been utilized to image trabecular bone structure in healthy and metastatic disease [ 34 ] . A number of studies have evaluated bone marrow vascularization using dynamic contrast-enhanced MRI techniques [ 35 ] .…”

The Agfa Mayneord lecture: MRI of short and ultrashortT2andT2* components of tissues, fluids and materials using clinical systems

“…Evidence of iron deposition can be seen in intervertebral discs in thalassaemia [102]. Sclerotic metastases and cement after vertebroplasty have been identified [103,104]. The structure of the annulus fibrosus can be demonstrated (Figure 7).…”
