For the diagnosis of rare and complex diseases, Medical Imaging Equipment faces many challenges in improving early detection and accurate diagnosis:
1. Complexity of disease characteristics:
Atypical symptoms: Rare and complex diseases often have diverse and atypical symptoms, which makes it difficult to diagnose based solely on imaging features. For example, some rare neurological diseases may have abnormal brain imaging that is similar to some characteristics of common diseases, which can easily cause confusion. Doctors need to make judgments based on a combination of clinical symptoms, family history and other information, which places higher demands on the diagnostic accuracy of Medical Imaging Equipment.
Special or tiny lesion sites: The lesions of some rare diseases are relatively special, and conventional Medical Imaging Equipment may find it difficult to clearly capture lesion information. For example, some rare endocrine diseases may have lesions in tiny glands or tissues, and ordinary imaging examinations may not be able to detect abnormalities, requiring higher resolution equipment or special imaging technology.
2. Limitations of imaging technology:
Imaging quality is affected by many factors: the patient's physical condition (such as obesity, metal implants in the body, etc.), body position and degree of cooperation during the examination, etc., may affect the quality of medical images, and thus affect the accuracy of diagnosis. For patients with complex diseases or poor physical conditions, it is often challenging to obtain high-quality images.
The accuracy of functional imaging needs to be improved: Although functional medical imaging technology can provide information about the functional metabolism of tissues and organs, the accuracy and repeatability of these technologies still need to be further improved. For example, positron emission tomography (PET) may be interfered by factors such as inflammation when detecting the metabolic activity of certain rare tumors, resulting in false positive results.
3. Lack of data and experience:
Rare disease imaging data is scarce: Due to the extremely low incidence of rare diseases, Medical Imaging Equipment has relatively few case data to refer to during the diagnosis process. This limits the application of big data-based artificial intelligence-assisted diagnosis technology in the field of rare diseases, and it is difficult to establish an accurate diagnostic model. For example, some rare genetic diseases may lack sufficient samples of their imaging features in the existing database, resulting in the inability of the diagnostic system to accurately identify them.
Insufficient doctor experience: The diagnosis of rare and complex diseases requires doctors to have rich experience and expertise. However, due to the rarity of these diseases, many doctors have few opportunities to come into contact with them in their daily work, and their knowledge and understanding of their imaging characteristics are not deep enough, which may lead to misdiagnosis or missed diagnosis.
4. Equipment cost and accessibility:
High-end equipment is expensive: Advanced Medical Imaging Equipment is expensive, which is difficult for some primary medical institutions or areas with limited resources to afford. Therefore, patients in these areas may not be able to obtain high-quality medical imaging examinations in a timely manner, affecting the early detection and diagnosis of rare and complex diseases.
Uneven distribution of equipment: High-quality Medical Imaging Equipment is mainly concentrated in large hospitals and developed areas, which leads to an uneven distribution of medical resources. Patients in remote areas and primary medical institutions may need to travel long distances to hospitals in large cities for examinations, which increases the burden on patients and delays the diagnosis and treatment of diseases.
