The mean ADC values for breast cancer were significantly different from that of normal breasts. The mean ADC value for breast cancer did not significantly correlate with cancer cellularity but did correlate with histological types.

DW-MRI may be useful for detecting breast cancer in a wide age group of women, including young women with dense mammary glands.

In this study, a single dose of gadobutrol was shown to be noninferior to a double dose of gadoteridol at detecting brain metastases, and could be effectively used for treatment planning in patients eligible for SRS. A dose of gadobutrol 0.1 mmol/kg BW is recommended as the clinical dose for the detection of brain metastases.

The positive detection rate on FDG-PET/CT was insufficient for determining an indication of SNB. However, use of an appropriate cut-off for SUV(max) (the positive rate was 90.9% with a cut-off of 2.0) and exclusion of surgically biopsied cases may achieve a clinically applicable positive detection rate.

This application can transform a smartphone into a valuable tool that is capable of objectively and accurately assisting CT-guided puncture procedures.
