Which statement about ACR Safety Zones 1 and 2 is correct? Both Zones 1 and 2 lie outside the 5 Gauss line. Patient safety screening is required before entering Zone 2 The general public should not be admitted to Zone 1; it is only for MR patients and their families. Patients wit...
limitations, primarily associated with the interpretation of equivocal PI-RADS 3 lesions and with the debated role of Dynamic Contrast Enhanced-Magnetic Resonance Imaging (DCE-MRI), which is only used to upgrade peripheral PI-RADS category 3 lesions to PI-RADS category 4 if enhancement is focal....
Table 2 shows the distribution of PI-RADS scores, PSA densities, lesion sizes, zones, and locations grouped by the first MRI-targeted biopsy core revealing the most relevant histopathologic diagnosis. Table 2 Distribution of PI-RADS v2.1 scores, PSA densities, lesion sizes, zones, and locations...
These authors were also able to observe how the distribution of water in the xylem and phloem zones changed throughout the dehydration process. Besides birch tree branches, similar results were observed in leaves, stems, branches and roots of other herbaceous plants and trees [10, 37, 54,55,...
On T1-W (weighted) images, AVN classically presents with acrescentic band of low signal in the subchondral femoral head bone marrow. This band is thought to represent the interface between thenecrotic and reparative zones. On T2 weighted and inversion recovery sequences, subacute AVN classically ...
However, few studies have examined the intramammary distribution of MRI-detected lesions in detail by dividing them into zones with third-look US using RVS. In the report by Nakano et al., supine MRI was performed first and prone MRI was not mandatory [16]. In this study, prone MRI was...

Cancers localized in the peripheral zone are more frequent4 and have a different MRI appearance3 compared to the cancers localized in the central (CZ) or transitional zones (TZ), the TZ and CZ together constituting the central gland (CG). Recent guidelines for scoring of PCa incorporate dif-...
Our prior study showed that systematic biopsy outside of the target lesion only detected csPCa in 21% of the cohort and that by omitting this biopsy, only 3% of our cohort would have had csPCa missed completely after excluding overlapping systematic biopsy cores into the MRI target zones [7...
which had been transformed into fibrous connective tissue. Granulation tissue with calcifications and osseous callus at its base was noted in reparative zones. The deposition of osteoid matrix is often perceived as subtle punctate calcific densities within the labrum and the femoroacetabular joint space...
