No significant differences were found between the area under the receiver operating characteristic curve of the digital and that of the conventional radiography method for almost all investigated criteria .The only exception （例外；异议）was mediastinal abnormalities, for which the digital method provided better results than the conventionvl method (P<0.05)Invasive breast cancer detection by mammography may be improved through attention to correct positioning.For CT of the brain, there are there standard reference lines; the orbitomeatal line, the Reid baseline, and the supraorbitomeatal line. The orbitomeatal line runs through the external canthus and the center of the external auditory meatus. This is the most widely used line, because acquisition of fewer sections is necessary to cover the entire brain. The Reid baseline runs though the inferior orbital wall and the superior border of the external auditory meatus. This line is paraller to the optic nerve and provides the best demonstration of the orditai contents. The supraorbitomeatal line runs through the superior orbital wall and the center of the external auditory meatus. This line approximately parallels the skull base. We developed reference lines for use at MR imaging that are analogous to the three standard reference lines used at CT, on the basis of anatomic landmarks that are visible on midsagittal MR images. These lines can be used to prescribe subsequent oblique axial sequences.During the past decade , many investigators have addressed the feasibility of picture archiving and communication system (PACS) as an alternative to film-based radiology. To successfully implement the PACS, a number of factors such as film resolution, interpretation conditions, and a cost-effective viewer system must be taken into consideration. The most important clinical criterion for using the PACS technology is the ability to achieve acceptable accuracy when interpreting radiologic images at a soft-copy viewing workstation. Most previous reports have focused on a comparison of observer performance with soft-copy and hard-copy imajes, and such studies have been performed using chest radiography. However, observer performance in projection radiography of another anatomic section must also be compared to achieve that the PACS can completely replace film-based radiology.CT in an invaluable tool in the diagnosis of the chest diseases with high-resolution CT (HRCT) providion exquisite visualization of the pulmonary interstitium. However, CT examinations do not come without a cose.. A report from the 2002 National Conference on Dose Reduction in CT indicates that CT now represents the largest single source of medical radiation exposure. Although CT constitutes only 15% of the total number of examinations in some university departments, it can account for 70% of the dose delivered.。

医学影像学英语Medical ImagingMedical imaging plays a crucial role in the diagnosis and treatment of various medical conditions. It is a branch of medicine that utilizes different imaging techniques to create visual representations of the interior of the body. These images help healthcare professionals to identify and diagnose diseases, plan appropriate treatment, and monitor the effectiveness of interventions. In this article, we will explore the importance of medical imaging in modern healthcare and discuss some of the commonly used imaging modalities.X-ray imaging is one of the oldest and most commonly used imaging techniques in medicine. It involves exposing the body to a small dose of ionizing radiation to create images of the internal structures such as bones and soft tissues. X-rays are frequently used to diagnose fractures, pneumonia, and certain types of cancer. Despite its widespread use, x-ray imaging has limitations in visualizing certain structures and tissues, such as the brain and blood vessels.Computed tomography (CT) is another valuable imaging modality that utilizes x-rays to produce detailed cross-sectional images of the body. CT scans are especially useful for detecting tumors, internal bleeding, and injuries to internal organs. The high-resolution images generated by CT scans provide healthcare providers with valuable information for surgical planning and treatment monitoring. However, the use of ionizing radiation in CT scans raises concerns about potential health risks, especially with repeated exposures.Magnetic resonance imaging (MRI) is a non-invasive imaging technique that uses a strong magnetic field and radio waves to create detailed images of the body's organs and tissues. MRI is particularly useful for visualizing soft tissues, such as the brain, spinal cord, and muscles. It is an essential tool in the diagnosis of neurological disorders, musculoskeletal injuries, and certain types of cancer. Unlike x-ray and CT imaging, MRI does not involve ionizing radiation, making it a safer option for imaging pregnant women and children.Ultrasound imaging, also known as sonography, uses high-frequency sound waves to create real-time images of the body's internal organs. Ultrasound is commonly used to monitor fetal development during pregnancy, diagnose abdominal conditions, and guide minimally invasive procedures. It is a safe and cost-effective imaging modality that allows healthcare providers to visualize the anatomy and function of organs in real-time. However, ultrasound has limitations in imaging structures that are located deep within the body or obscured by gas or bone.Nuclear medicine is a specialized branch of medical imaging that involves the use of radioactive substances to diagnose and treat diseases. This imaging modality includes techniques such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT). Nuclear medicine is essential for evaluating cancer, heart disease, and neurological disorders by detecting changes in cellular function and metabolism. While nuclear medicine imaging provides valuable information, it requires careful handling of radioactive materials and exposure risks for both patients and healthcare providers.In conclusion, medical imaging plays a critical role in modern healthcare by enabling the non-invasive visualization of the body's internal structures. Each imaging modality has its unique advantages and limitations, allowing healthcare providers to choose the most appropriate technique based on the patient's clinical condition. As technology continues to advance, medical imaging will continue to evolve, providing more accurate diagnostic information and improving patient outcomes.。
