Why Does Clinical History Matter Before an Imaging Test?

Patients are questioned about their symptoms, medical history, any previous treatment, medicines, allergies, and health-related issues before getting an imaging test. This seemingly innocuous information is vital in guiding healthcare professionals to the right type of imaging and interpreting the results properly.

PET-CT, CT, MRI, and ultrasound are imaging tests used to get detailed pictures of the body. These diagnostic scans are chosen based on the patient's clinical history. It is helpful for the radiologist to have this information so they can concentrate on the area of concern and diagnose the condition. Molecular Diagnostics and Therapy offers modern diagnostic services and provides timely reports so that doctors can start treatment promptly.

What Is Clinical History?

Clinical history provides information regarding the current and past health of the patient. This includes indication for the scan, symptoms, history, surgeries, treatment, medications, allergies, and significant family or personal history of the patient. A patient with chronic back pain should bring other clinical reports if having an MRI after an injury. This background knowledge aids the doctors in having information that guides them in understanding the condition.

How Clinical History Helps With PET-CT Scan Preparation?

The preparation for PET-CT scans differs depending on the type of scan. Your health care team needs to know about other health issues, previous cancer treatments, infections and/or medications, as well as diabetes to assess you properly. Patients should prepare according to the instructions they are given by their health care provider or diagnostic center. This can also involve directions regarding food, fluids, medications, and physical exertion before the exam. Full clinical information of the patient allows the healthcare team to have an understanding of the patient's condition. 

How Clinical History Helps With MRI Scan Preparation?

The clinical history of the patient helps in preparing and assists in the setup for the MRI scan. There are also other aspects of MRI scan preparation that are dependent upon the type of examination. Patients might be asked about previous surgeries, implants, pacemakers, metal objects in the body, medications, pregnancy, as well as any other medical conditions before an MRI. Certain implants and devices also need special evaluation. 

Why Do Doctors Ask About Previous Treatments?

The appearance of the tissues should be compared with previous reports. Sometimes changes made by surgery, radiation therapy, chemotherapy, or other therapies can also be seen on a scan. If the examiner has a history of treatment, they are able to compare this information with other information to determine that the changes indicated by the MRI are typical of certain treatments. This is especially true if imaging is undertaken as a follow-up investigation for a known disease.

Why Medicines and Allergies Matter?

In some imaging tests, a special dye or other substances might be used, and information regarding a history of allergic reaction, kidney disease, present medications, and any other health conditions is beneficial in the safe planning of the examination. Medications prescribed by the doctor must not be stopped unless it is specifically advised.

Why Symptoms Should Be Explained Clearly?

The indication for the scan is relevant to the clinical history. Patients should report pain, swelling, changes in weight or function, bleeding, headaches, or any other concerns to their doctor. Please also note the onset of symptoms, or if they are getting worse. Clear information allows the healthcare team to have a better understanding of the anatomical scan they are looking to investigate.

Conclusion

Clinical history is an important part of preparing for an imaging test. Information about symptoms, previous diseases, surgeries, treatments, medicines, allergies, implants, and earlier scans can help the healthcare team plan the examination and understand the images more accurately. Whether you are preparing for a PET CT scan, CT scan, or MRI, following the preparation instructions provided by your healthcare team is important. Always share complete and accurate medical information before the examination.
