What are the disadvantages of cone-beam breast CT?

Generally, the disadvantages of cone-beam breast CT include high radiation dose, high cost, long examination time, relatively low breast tissue resolution, and limited range of applications. A detailed analysis is as follows:

1. High Radiation Dose

Cone-beam breast CT requires the use of X-rays, thereby exposing patients to radiation. The radiation dose is typically higher than that of conventional mammography or breast ultrasound, necessitating careful consideration of the risks and benefits.

2. High Cost

Cone-beam breast CT equipment is relatively expensive and demands advanced technical expertise, specialized training, and regular maintenance. These factors contribute to higher costs and may limit its availability in certain healthcare facilities.

3. Long Examination Time

Compared to conventional mammography, cone-beam breast CT requires a longer examination duration. This may require patients to remain in a fixed position for an extended period, potentially causing discomfort.

4. Lower Breast Tissue Resolution

Compared to magnetic resonance imaging (MRI), cone-beam breast CT may offer lower resolution of breast tissue. This means that in some cases, it may not provide the same level of detailed information as MRI.

5. Limited Applicability

Cone-beam breast CT is suitable for diagnosing specific breast conditions, such as small tumors. For other breast diseases or abnormalities, additional imaging modalities may be required for comprehensive evaluation.

If a patient experiences any discomfort or adverse symptoms after undergoing cone-beam breast CT, it is recommended to seek medical attention at a hospital promptly to avoid delays in diagnosis and treatment.
