To distinguish malignant versus benign lymph nodes between 4 and 9 mm in size, with the same optimal ADC b0 1000 threshold of 0.94 × 10−3 mm/sec, 76% Se, 94% Spe, 92% accuracy, 73% PPV, and 95% NPV were achieved, while 7% Se, 99.5% Spe, 85% accuracy, 75% PPV, and 85% NPV were found for morphological criteria.
Fraction C was similarly subjected to SPE using C-18 SPE cartridge and sequential fractions recovered were fractions CA and CB.
Bond Elut C18 Solid phase extraction (SPE) cartridges (500 mL/6 mL), Bond NH2 SPE cartridges (500 mL/3 mL), Poly-Sery HLB SPE cartridges (60 mL/3 mL) and Bond Carbon-GCB SPE cartridges (250 mL/3 mL) were purchased from CNW, (Shanghai, China).
For predicting recurrent cancer, combined T2WI and DWI showed Se 62%, Spe 97%, PPV 91%, and NPV 81%, whereas T2WI alone displayed Se 25%, Spe 92%, PPV 57%, and NPV 74%.
The crude mixture was purified by C18 SPE.
Google offers the Google Cloud Dataflow8 SPE as a service in the Google Cloud Platform.
The resulting solution was then pushed through a preconditioned C18 SPE cartridge (10 mL EtOH, 20 mL H2O, dried).
After centrifugation, the separated methanol was diluted to 50 mL with double-distillated water and passed through the C18 SPE cartridge.
Method 1, acetoacetate extract; method 2, n-butanol extract; method 3, 70% ethanol treatment; method 4, SPE column eluted with methanol; method 5, HPD100 column eluted with ethanol.
