Dr Balaji Ganeshan presents TexRAD at the prestigious Beijing Society of Radiology Conference.
On Saturday September 9th 2017, Dr Balaji Ganeshan, CEO of TexRAD Ltd and Director of New Business at Feedback Plc gave a keynote lecture entitled “TexRAD Texture Analysis of CT and MR images – ready for prime time?” at the prestigious Beijing Radiation Academic Annual Conference.
Dr. Ganeshan spoke on CT and MRI texture analysis in cancer imaging which is a very topical area of interest in medical imaging and TexRAD is at the forefront of this development. Evidence that currently supports the potential use of TexRAD in different clinical applications and its utility as part of the qualification process for its use in routine clinical practice was further discussed.

Endometrial Carcinoma: MR Imaging-based Texture Model for Preoperative Risk Stratification – Feedback (FDBK).
Feedback (FDBK) – Endometrial Carcinoma: MR Imaging-based Texture Model for Preoperative Risk Stratification – Preliminary Analysis. Source 
Ueno Y, et al. Radiology. 2017.
PURPOSE: To evaluate the associations among mathematical modeling with the use of magnetic resonance (MR) imaging-based texture features and deep myometrial invasion (DMI), lymphovascular space invasion (LVSI), and histologic high-grade endometrial carcinoma.
MATERIALS & METHODS: Institutional review board approval was obtained for this retrospective study. This study included 137 women with endometrial carcinomas measuring greater than 1 cm in maximal diameter who underwent 1.5-T MR imaging before hysterectomy between January 2011 and December 2015. Texture analysis was performed with commercial research software (TexRAD) with manual delineation of a region of interest around the tumor on MR images (T2-weighted, diffusion-weighted, and dynamic contrast material-enhanced images and apparent diffusion coefficient maps). Areas under the receiver operating characteristic curveand diagnostic performance of random forest models determined by using a subset of the most relevant texture features were estimated and compared with those of independent and blinded visual assessments by three subspecialty radiologists.
RESULTS: A total of 180 texture features were extracted and ultimately limited to 11 features for DMI, 12 for LVSI, and 16 for high-grade tumor for random forest modeling. With random forest models, areas under the receiver operating characteristic curve, sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were estimated at 0.84, 79.3%, 82.3%, 81.0%, 76.7%, and 84.4% for DMI; 0.80, 80.9%, 72.5%, 76.6%, 74.3%, and 79.4% for LVSI; and 0.83, 81.0%, 76.8%, 78.1%, 60.7%, and 90.1% for high-grade tumor, respectively. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of visual assessment for DMI were 84.5%, 82.3%, 83.2%, 77.7%, and 87.8% (reader 3).
CONCLUSION: The mathematical models that incorporated MR imaging-based texture features were associated with the presence of DMI, LVSI, and high-grade tumor and achieved equivalent accuracy to that of subspecialty radiologists for assessment of DMI in endometrial cancers larger than 1 cm. However, these preliminary results must be interpreted with caution until they are validated with an independent data set, because the small sample size relative to the number of features extracted may have resulted in overfitting of the models.

Prostate-specific membrane antigen PET-MRI validation of MR textural analysis for detection of transition zone prostate cancer? – Feedback (FDBK)
Feedback (FDBK) – Prostate-specific membrane antigen PET/MRI validation of MR textural analysis for detection of transition zone prostate cancer? Source
Bates A, et al. Eur Radiol. 2017.
OBJECTIVES: To validate MR textural analysis (MRTA) for detection of transition zone (TZ) prostate cancer through comparison with co-registered prostate-specific membrane antigen (PSMA) PET-MR.
METHODS: Retrospective analysis was performed for 30 men who underwent simultaneous PSMA PET-MR imaging for staging of prostate cancer. Thirty texture features were derived from each manually contoured T2-weighted, transaxial, prostatic TZ using texture analysis software that applies a spatial band-pass filter and quantifies texture through histogram analysis. Texture features of the TZ were compared to PSMA expression on the corresponding PET images. The Benjamini-Hochberg correction controlled the false discovery rate at <5%.
RESULTS: Eighty-eight T2-weighted images in 18 patients demonstrated abnormal PSMA expression within the TZ on PET-MR. 123 images were PSMA negative. Based on the corrected p-value of 0.005, significant differences between PSMA positive and negative slices were found for 16 texture parameters: Standard deviation and mean of positive pixels for all spatial filters (p = <0.0001 for both at all spatial scaling factor (SSF) values) and mean intensity following filtration for SSF 3-6 mm (p = 0.0002-0.0018).
CONCLUSION: Abnormal expression of PSMA within the TZ is associated with altered texture on T2-weighted MR, providing validation of MRTA for the detection of TZ prostate cancer.
KEY POINTS: Prostate transition zone (TZ) MR texture analysis may assist in prostate cancer detection. • Abnormal transition zone PSMA expression correlates with altered texture on T2-weighted MR. • TZ with abnormal PSMA expression demonstrates significantly reduced MI, SD and MPP.
