Particularly, there was a significant difference in PFS between patients with interim score 12 and those with score 3. Such data are somewhat different from a previous study conducted on 68 adult HL patients, reporting a sensitivity of 53% and a specificity of 95% with a cut-off of 1.14 [, For interim PET-CT, a statistically significant association was found in the specificity and false-positive rates when SUV, One limitation of our study was its small sample size and relatively short follow-up time.

The metabolic activity in PET/CT is usually assessed with the Deauville Score (DS), a 5-point system to categorize FDG avidity. Mixed cellularity Hodgkin can occur at any age, although it is most common in adults between the ages of 55 and 74, as well as children under the Nucl. Receiver operating characteristic (ROC) curves were generated, and the area under the ROC curve was calculated to assess the diagnostic accuracy of rPET in detecting a positive response, along with the corresponding cut-off scores. The extent and frequency of follow-up specifically depend on the histologic subtype of lymphoma. One of the coauthors, B.H.

Performance of Philips Gemini TF PET/CT scanner with special consideration for its time-of-flight imaging capabilities. It would also have been desirable to obtain data from a more consistent patient population with a consistent therapy regimen and identical time points of PET/CT. The feature median from NECT concordantly has a high sensitivity for DS4+ Hodgkin manifestations on two different scanners and thus could provide a surrogate for increased metabolic activity in PET/CT. 2018 Dec;24(12):2501-2508. doi: 10.1016/j.bbmt.2018.07.025. Kobe, C. et al.
