Predictive value of magnetic resonance imaging indications of spinal cord swelling for cervical spondylotic myelopathy prognosis.

Background: Magnetic resonance imaging (MRI) is the preferred examination approach for patients with suspected cervical spondylotic myelopathy (CSM).

Objective: To investigate the predictive value of MRI spinal cord swelling on the prognosis of decompression surgery in patients with CSM.

Methods: A retrospective analysis of 115 patients with CSM who underwent decompression surgery was performed.

Signal characteristics of normal adult bone marrow in whole-body diffusion-weighted imaging.

Background: Knowledge of the signal characteristics of normal adult bone marrow in whole-body diffusion-weighted (DW) images (WB-DWI) is essential for correctly interpreting DW images in clinical practice; however, these factors have not yet been clearly determined.

Purpose: To evaluate the signal characteristics of normal adult bone marrow in WB-DWI, to correlate these characteristics with age and gender, and to determine the causes of these phenomena.

Material And Methods: Ninety-eight healthy volunteers underwent WB-DWI (b = 0 and 800 s/mm(2)).

Differentiating benign from malignant bone tumors using fluid-fluid level features on magnetic resonance imaging.

Objective: To analyze different fluid-fluid level features between benign and malignant bone tumors on magnetic resonance imaging (MRI).

Materials And Methods: This study was approved by the hospital ethics committee. We retrospectively analyzed 47 patients diagnosed with benign (n = 29) or malignant (n = 18) bone tumors demonstrated by biopsy/surgical resection and who showed the intratumoral fluid-fluid level on pre-surgical MRI.
