Table 3.

Studies reporting on prostate displacement induced by probe pressure. The first column details the first author and publication year. Δ indicates that the specific study was mentioned in the previous review paper [11], but these specific results were not discussed. The second column details the used system, while the third column provides the imaging modality with which the prostate displacement was assessed. The fourth and fifth column specify the number of examined patients and the assessed scans, respectively. The prostate displacement in all directions is listed in column 6 with a indicating results per 1 mm probe shift and in the final column the displacement vector can be found.
