Foreword
When we compiled the first edition of Clinical Body CT Diagnostics in 1985, we were not yet experienced in clinical practice, but for the urgent need of the majority of our colleagues, we managed to complete a timely and practical tool for the purpose of meeting the requirements of the field. 9 years on, we have gained more experience, and there have been many new developments in the international arena, which makes it absolutely necessary to republish a new edition that is rich in content and up to date with the progress of the times, new edition that keeps up with the progress of the times. The book is written by scholars with specialized experience and includes new chapters on cranial, cervical, osteoarticular, lymphomatosis, and the basics of magnetic **** vibration, among others. With the economic development of the country, CT has become quite popular in the country. On behalf of all the authors, I would like to dedicate this book "Clinical CT Diagnostics" to your work and study. Images are an important part of this book, and I would like to express my gratitude to the comrades in charge of charting in various organizations.

Chapter I Overview of Cranial CT Scanning Section I Cranial CT Scanning Techniques and Examination Methods I. Scanning Techniques of Cranial CT Cranial CT depiction techniques include: the use of X-rays; the selection of the position and level; the thickness and spacing of the layers; the scanning field; and the selection of the scanning time and post-processing. (I) Use of X-rays For areas with thicker bone, such as the posterior cranial recess and the saddle region either raise the mA or increase the kV, with the aim of improving the penetration ability of X-rays. When thin layers are used, the x-ray dose should also be increased in order to improve the signal-to-noise ratio. Pediatric craniography naturally reduces the x-ray dose. When the scanning time is shortened, the x-ray dose needs to be increased accordingly, but the heat capacity of the x-ray tube balloon must also be taken into account and sufficient cooling time given. When using dynamic scanning techniques, the decrease in x-ray dose helps to shorten the cooling time of the tube balloon. (ii) Positioning and level selection Conventional cranial CT scanning takes the auditory brow line (25° of the auditory orbital line), with the aim of including the largest part of the examination with the smallest number of examination levels. For some special lesions, the choice of level should be set in accordance with the need to fully expose the anatomical relationship of the examined area and the need for pathologic examination. For the examination of the posterior cranial recess, the parallel orbital line can reveal more of the cerebellum. For orbital examination, a parallel canthal line reveals the optic nerve, whereas a direct coronal section scan is best for visualizing the relationship between the optic nerve, ocular muscles, and bone. Pterygoid scanning, with levels parallel to the saddle floor, is most favorable for showing the pituitary gland in thin layers; direct coronal views, of course, are also suggestive of the superior border of the pituitary gland, the pituitary stalk, and the relationship of the pituitary gland to the saddle floor and cavernous sinus. When the cerebellar curtain lesion is not easy to identify the supratentorial or infratentorial, the coronal section after injection is favorable to show the relative relationship between the cerebellar curtain and the lesion, which is conducive to the localization and diagnosis of the lesion. For lesions in the parasagittal sinus or high convexity, the coronal section can show the relationship between the lesion and the bone to facilitate qualitative diagnosis. For temporal lobe lesions, since the conventional plane cannot show the whole temporal lobe and there are many artifacts in the middle cranial recess. Therefore, the auditory-orbital line is tilted to the side of the head by 20, and the left and right projections are more conducive to diagnosis by exposing the temporal lobe in a single view. Furthermore, when selecting levels, care should be taken to avoid teeth, dentures, and thick bones that are prone to artifacts, all of which will improve the image, and this is most important when examining the saddle region in coronal view. Scanning in the sagittal plane is generally limited by the human body and machine conditions, so it is not used, but it is also very useful in displaying the conduit and saddle and other midline lesions. (C) Thickness and spacing of layers Cranial brain scans are generally 10 mm thick, and thin-layer scans are used to minimize the interference of partial volume effects, to detect small lesions, and, of course, to minimize artifacts in the posterior cranial recess. Thin-layer scans are generally used in the posterior cranial recess, the saddle region and the orbit. The layer thickness can be 5 mm, 2 mm or thinner, respectively. Successive scans of thin layers can also be used for the required high quality of reconstructed images. During dynamic CT scanning, the density of contrast agent at the same level is observed versus time with zero layer spacing. In second-generation CT where layer thickness cannot be adjusted, overlapping scans can be used with layer spacing less than layer thickness to prevent leakage of small lesions, generally with layer spacing equal ......
