Introduction to Quantitative T2

MATERIALS AND METHODS 30 patients with 32 uterine fibroids underwent an MRI study including a quantitative T2 relaxation time measurement prior to MRgHIFU treatment.

Quantitative T2*, R2* measurements were used to study the signal change of the phantom.

In addition, quantitative T2 relaxation time/T2 relaxation rate mapping characterizes myelin-related changes of the brain stem prenatally.

Quantitative T2 and DCE parameters were not associated with biochemical outcome.

PURPOSE To evaluate image quality and ability to detect PCa with quantitative T2-mapping and DWI in men with hip prosthesis undergoing prostate MRI.

The prepared samples were then scanned with quantitative T2* mapping, T2 fast spin-echo (FSE), T2 gradient-echo (GRE), fluid-attenuated inversion recovery (FLAIR), and susceptibility-weighted angiography (SWAN).

Ten sessions of traction resulted in a significant increase in quantitative T2 measurements of the NP in discs for Pfirrmann grade II-IV degeneration and remission of the patients' clinical symptoms in the following 6 months.

Similar to ADC values, quantitative T2 values could serve as a noninvasive biomarker to predict histological grades preoperatively.

Conclusions Quantitative T2 mapping differentiated WHO grade II glioma from HGG with moderate sensitivity and specificity.

A recent multicenter randomized study compared the use of C-ACT and microfracture and found that C-ACT exhibited significantly better results in several MOCART subscores and quantitative T2 mapping, indicating a histologically superior form of repaired cartilage compared with microfracture3.

Conclusion Our preliminarily results suggest that quantitative T2 mapping of the intra/extracellular water component was more sensitive than conventional FLAIR imaging to subtle cerebral tissue abnormalities, deserving to be further investigated in future clinical studies.

In our study, quantitative T2 mapping in patients who were positive and negative for hs-TnI [51 (47.

Quantitative T2 mapping does not require intravenous contrast injection, dedicated coil, or high field strength magnet as other techniques.

Objectives The aim of the study was to determine the quantitative T2 values in prostate tissue and evaluate them for detection and grading of prostate cancer.

Reduced hippocampal volume and elevated T2 signal are associated with MTS, and both quantitative T2 and volumetric measurements have been associated with hippocampal cellular loss that characterizes this condition.

Quantitative T2 values of PCa and benign tissue ROIs were measured.

Quantitative T2 values were measured with circular 2D ROIs in the solid tumor portion and also in the normal renal parenchyma (cortex and medulla).

• Quantitative T2* values can be obtained from DICOM data instead of k-space data.

Quantitative T2 can detect early biochemical cartilage changes, but its routine implementation is challenging.

To investigate whether quantitative T2-times depend on lumbar intervertebral disc (IVD) level.

In particular, T2* weighted MRI has proven to be a simple and useful method to assess placental health, either studying the quantitative T2* relaxation time or the relative change in the raw T2* weighted signal in response to a given challenge (the BOLD response).

The iron Prussian blue staining and quantitative T2-map MRI analysis showed that, compared with UA, UG, and U, the uptake of double antigen-targeted UAG probe demonstrated a 23.

High transverse relaxivity negative contrast agent synthesis, MSC labelling procedure, and quantitative T2∗ time measurement normalized with absolute bias correction are the key features of this protocol.

Structural OA features (osteophytes, bone marrow lesions, cartilage defects, Hoffa synovitis, patellar tendon abnormalities) and quantitative T2 measurements of cartilage composition were extracted from MRI.

After 4 weeks, both knees were examined by MRI with quantitative T2 mapping sequence, and the T2 relaxation times of cartilage and meniscus were measured.

The objective of this study was to determine the correlation between quantitative T2 mapping-based tendon healing and clinical outcomes during the first year after arthroscopic rotator cuff repair.

High resolution T2-weighted, T2*-weighted and quantitative T2 MRI was utilized to image NP delivery in real-time and determine the volume of distribution (VD) of NPs at multiple time points over the first 48 h post-CED.

Quantitative T2 mapping can be beneficial for tissue characterization and early diagnosis of tissue pathology but current T2 mapping techniques lack the capability to image near metal hardware.

Quantitative T2 imaging offers a non-invasive measurement of muscle oedema which could help improve the understanding of muscle pathology and potentially inform diagnosis (1).

Here, we analyze the effects of MT on MESE signal, alongside their impact on quantitative T2 measurements.

PURPOSE To investigate compositional changes of knee cartilage at the site of newly appearing cartilage lesions and the surrounding cartilage 1-4 years prior to lesion onset using quantitative T2-measurements.

Quantitative T2 and structural assessment of cartilage and meniscus, using a single 5-min qDESS scan, can distinguish between different grades of radiographic OA, demonstrating the potential of qDESS as an efficient tool for OA imaging.

OBJECTIVE The purpose of this study was to determine whether quantitative T2-weighted imaging and apparent diffusion coefficient (ADC) texture features of bladder cancer and extravesical fat are predictive of muscle invasive bladder cancer (category ≥ T2) and extravesical (category ≥ T3) disease after transurethral resection of a bladder tumor (TURBT).

Quantitative T2-analysis was performed in the femorotibial joint cartilage in 4 slices with each 10 regions of interest (ROIs).

Multiple MR parameters, including the number of fascicles (N), fascicles diameter (FD), total fascicles area (FA), epineurium area (EA), total nerve area (NA), fascicles to nerve ratio (FNR) and quantitative T2 and proton density (PD) were investigated on high resolution MR images of the distal tibial nerve.

Quantitative T2 and T1rho relaxation times of ACL graft may offer a non-invasive method for monitoring graft maturation that correlates with patient-reported knee function after ACL reconstruction.

MRI consisted of morphological measures from T2-weighted imaging, quantitative T2-imaging, and diffusion weighted imaging (DWI) at 1, 30, and 90 days post injury (dpi).

The three case studies presented in this thesis have experimentally investigated and evaluated the analytical efficacy of the transverse relaxation based techniques and quantitative T2 measurements.
