MR urography achieves comparable performance compared to CT urography.

<p>Three-dimensional Volume Rendering reconstruction of the urinary tract against a faded background from the images obtained with CT urography (A) and MR urography (B) excretory phases.MR urography achieved a comparable diagnostic performance.</p

Imaging Features and ADC values of Histologically Confirmed Metastatic Axillary LNs.

<p>Imaging Features and ADC values of Histologically Confirmed Metastatic Axillary LNs.</p

The ADC readings were congruent between observers (A) and (B).

<p>Receiver operating characteristics (A) and scatter plot (B) of readings from two observers (n = 56) with ROIs including information of the mean, standard deviation, minimum, and maximum values. Diagonal segments result from ties.</p

Receiver operating characteristics of readings with two types of ROI information (n = 33).

<p>First reading with no information on minimum value in the ROI (standard ROI), second reading with information of the mean, standard deviation, minimum, and maximum values (detailed ROI) improved the accuracy. Diagonal segments result from ties.</p

A core biopsied lymph node.

<p>Final histopathology indicating true-positive US and DWI findings with metastases (A-F). Imaging of a 62-year-old female with a 31 mm BI-RADS 5 tumour in the right breast. LN that was targeted for core biopsy on axillary US measured 12 x 29 mm with a cortical thickness of 9 mm. STIR, DWI, US and ADC (A,B,D,E) images of this histopathologically confirmed metastatic LN having ADCs of 0.436 x 10⁻³ mm2/s and 0.789 x 10⁻³ mm2/s according to two observers; both of these values were below the threshold of 0.812 x 10⁻³ mm2/s. Histolopatholocigal images (C,F) of core biopsied LN with visual biopsy channel (arrow). Final histopathology indicated true-positive US and DWI findings with metastatic involvement.</p

The value of MR imaging at different time intervals.

<p>MR urography maximum intensity projections at 5 min (A), 10 min (B) and 15 min intervals after the administration of contrast show no difference in visualization of the upper urinary tract (UUT) at MR-combined different time intervals. Different segments can be better visualized at different time intervals therefore improving the overall UUT visibility and provided comparable performance with CT urography (D, volume rendering reconstruction).</p
