Lumbar Spine MRI

该数据集包含一个匿名的临床MRI研究或一组515有症状的背痛患者的扫描。每个患者数据可以有一个或多个与之相关的MRI研究。每个研究都包含切片，从最低的三个椎骨和最低的三个ivd的矢状或轴向视图中拍摄的单个图像。轴向视图切片主要取自最后三个ivd-包括最后一个椎骨和the骨之间的一个。最后一个IVD的切片的方向遵循脊柱的曲线，而其他IVD的切片通常以块 (即彼此平行) 制成。从IVD的顶部到底部，每个IVD有四到五个切片。许多顶部和底部切片穿过椎骨，留下一到三个切片干净地切开IVD，并纯粹显示该IVD的图像。在大多数情况下，轴向视图中的切片总数在12到15之间。但是，在某些情况下，可能有多达20个切片，因为该研究包含超过最后三个椎骨的切片。矢状面扫描也有所不同，但都至少包括最后七个椎骨和骶骨。尽管椎骨的数量各不相同，但每次扫描始终包括前两个骶骨链接。在我们的数据集中一共有48,345个MRI切片。大多数切片的图像分辨率为320x320像素，但是，三项研究中的切片分辨率为320x310像素。所有切片中的像素的精度为每个像素12位，高于标准的8位灰度图像。具体地，对于所有轴向切片，均匀地4毫米切片厚度，并且4.4毫米相邻切片之间的中心到中心距离。水平和垂直像素间距在所有轴向视图切片上均匀地0.6875毫米。大多数MRI研究是在患者处于头第一仰卧位的情况下进行的，其余的则是在患者处于脚第一仰卧位的情况下进行的。每项研究可以持续15到45分钟，患者可能会在不同的时间或不同的天数进行一项或多项与之相关的研究。

This dataset contains anonymized clinical MRI studies or scans from 515 symptomatic back pain patients. Each patient may have one or more associated MRI studies. Each study contains slices: individual images acquired from sagittal or axial views of the lowest three vertebrae and the lowest three intervertebral discs (IVDs). Axial view slices are primarily taken from the final three IVDs—including one between the final vertebra and the sacrum. Slices for the final IVD follow the curvature of the spine, while slices for other IVDs are typically acquired in blocks (i.e., parallel to one another). From the top to the bottom of an IVD, there are 4 to 5 slices per IVD. Many top and bottom slices pass through vertebrae, leaving 1 to 3 slices that cleanly section the IVD and purely display images of that IVD. In most cases, the total number of slices in an axial view ranges between 12 and 15. However, in some cases, there may be up to 20 slices, as the study includes slices beyond the final three vertebrae. Sagittal scans also vary, but all include at least the final seven vertebrae and the sacrum. Although the number of vertebrae differs, every scan consistently includes the first two sacral segments. There are a total of 48,345 MRI slices in our dataset. Most slices have an image resolution of 320×320 pixels; however, slices from three studies have a resolution of 320×310 pixels. The pixel precision across all slices is 12 bits per pixel, which is higher than standard 8-bit grayscale images. Specifically, for all axial slices, the slice thickness is uniformly 4 mm, and the center-to-center distance between adjacent slices is 4.4 mm. The horizontal and vertical pixel spacing is uniformly 0.6875 mm across all axial view slices. Most MRI studies were performed with the patient in the head-first supine position, while the remaining studies used the foot-first supine position. Each study can last from 15 to 45 minutes, and patients may undergo one or more associated studies at different times or on different days.
