The findings at CT-diskography (CT-D), including recording of the pain introduced at contrast injection, were compared with plain CT and MR imaging in 111 disks in 101 patients aged 18 to 68 years.
Six disks which were normal at CT had normal CT-D and 5 of them had normal signal on MR imaging. The degree of annular degeneration and the depth of the annular tears were significantly associated with each other and with loss of disk height, but not with size or location of the hernias. Only the depth of the tears was significantly associated with loss of signal on MR. However, frequently complete annular tears and severe annular degeneration were seen in association with small bulges and hernias, even in disks with normal or slightly reduced signal on MR and with normal height. The type and intensity of the pain introduced were associated with each other and with the depth of the annular tears, but not with the degree of annular degeneration, size of the hernia or the MR signal intensity of the disks.
Annular degeneration and tears on one hand, and the type and intensity of pain introduced on the other, seem to be related than separate phenomena.
在101例年龄在18至68岁的患者中，将CT椎间盘造影（CT-D）的检查结果（包括注射造影剂时诱发疼痛的记录）与平扫CT及磁共振成像（MR成像）对111个椎间盘的检查结果进行比较。
CT检查正常的6个椎间盘，其CT-D检查结果也正常，其中5个在MR成像上信号正常。椎间盘环的退变程度与椎间盘环撕裂的深度显著相关，且与椎间盘高度的丢失显著相关，但与疝的大小或位置无关。仅撕裂深度与MR成像上的信号丢失显著相关。然而，即使在MR成像信号正常或略有降低且高度正常的椎间盘中，也经常见到完全的椎间盘环撕裂和严重的椎间盘环退变与小的椎间盘膨出和疝同时存在。诱发疼痛的类型和强度彼此相关，且与椎间盘环撕裂的深度相关，但与椎间盘环退变程度、疝的大小或椎间盘的MR信号强度无关。
一方面，椎间盘环退变和撕裂，另一方面，诱发疼痛的类型和强度，似乎是相关的，而非独立的现象。
