If one has unexplainable pain, an injury, or symptoms that are worsening, the identification of the root cause becomes crucial for effective treatment. Physical examination and the medical history of a patient are essential sources of information; however, there are situations when doctors require a more in-depth look at the condition of a person’s body. That is when medical imaging becomes relevant.The use of imaging services provides the possibility to examine internal organs, identify any injuries, and diagnose medical conditions independently of the symptoms experienced by the patient. In case it is needed, doctors will suggest taking X-rays, ultrasound, CT or MRI scans depending on the case.There are different applications of medical imaging, from investigating joint pain to diagnosing and analyzing the injuries in the emergency room. The knowledge of what medical imaging is can be helpful for patients.
What Are Medical Imaging Services?
Specialized medical equipment is employed for creating visual representations of the structures found within the body. Medical images together with symptoms, examination results, medical history, and lab results are used by doctors to try and pinpoint the causes of an illness.Various types of imaging have various purposes. The most suitable type of imaging varies according to the part of the body to be imaged, possible diagnosis, the age of the patient, and the urgency of the matter.
Types of medical imaging can be exemplified as:
- X-rays: Used mostly for the diagnosis of fractures, joint problems and different chest diseases.
- CT scans: These are cross-sectional images used for the evaluation of inner injuries and different illnesses.
- Ultrasound: This type of imaging uses sound waves to look at various organs, soft tissues, the movement of blood, and pregnancy-related diseases.
- MRI: This makes use of a powerful magnetic field together with radio waves to form images of various organs, the brain, the spinal cord, and joints.
Imaging is not necessary in all cases. The need for imaging and its type are decided by the healthcare practitioner.
1. Helps Doctors Identify Injuries
Medical imaging can assist in assessing injuries sustained through falls, sporting events, accidents involving vehicles, among others.There are some injuries that can easily be detected during a physical examination while there are some injuries that are more difficult to detect as they involve structures that cannot be examined externally. Medical imaging can aid in assessing such possibilities.For instance, the X-ray can show bone fractures after a fall while a CT scan will further assess any possible injury at that particular site. The MRI can be used to assess certain ligament and tendon injuries.Findings obtained through medical imaging can guide health practitioners in making a decision on whether to treat the patient through immobilization, medication, referral, surgery, or any other treatment modality.However, just because the medical imaging shows no injury, it does not necessarily mean that there is no injury in the patient's body.
2. Supports Faster Evaluation During Emergencies
In case of an emergency situation, the medical specialist can have to make a diagnosis of the disease quite rapidly. The information received from the medical imaging would be quite difficult to receive in another way.
Depending on the symptoms of the disease and the likely diagnosis, the scanning can be used for researching such conditions as:
- internal bleeding because of severe trauma;
- certain types of bone fractures;
- a stroke or the bleeding in the brain;
- the injuries of the chest and certain diseases of the lungs;
- the reasons of severe abdominal pain;
some problems with the work of internal organs.It depends on the health condition of the patient what type of scanning he will need. So, for instance, if the specialist needs to see detailed pictures of the injury, the CT scanning is needed, but the X-rays are sufficient if the specialist wants to find out some bone fractures.Medical imaging can be a part of the emergency examination, which includes vital signs control, the tests of the blood, the immediate treatment, and consultations with specialists.However, if the symptoms are life-threatening, the patient shouldn't attempt to conduct the scanning first.
3. Helps Investigate Unexplained Symptoms
However, all the medical conditions are not associated with any clear physical injury. The pain, inflammation, and other unknown symptoms should be examined if there were no conclusions made during the first examination.The use of medical images will allow the doctor to examine the areas of body where the aforementioned signs occur and to understand if any other additional examination is required.
Examples:
- An ultrasound can be used for the diagnosis of some abdominal disorders or lumps in soft tissues.
- X-ray can be used for the diagnosis of some bone and chest disorders.
- CT scan can be used for the examination of some abdominal pains.
- MRI can be used for the examination of some neurological and joint disorders.
- Medical imaging cannot always help to diagnose the causes of all the mentioned symptoms. There are certain diseases that are easier to examine with the use of laboratory and physical tests.
The aim is to find the right test which will be able to provide the correct answer for the medical issue without conducting unnecessary tests.
4. Provides Information for Treatment Planning
The accurate diagnosis helps doctors to choose the right way to act. The medical imaging helps the doctor to know where exactly and how much some abnormality is, which information can influence further steps.For example, the imaging of a fracture will help the doctor to understand if the bones are aligned and whether there should be called some specialists to treat the condition.The medical imaging helps doctors to analyze some tumors, follow some diseases and evaluate how some treatment influenced them.Sometimes the medical imaging needs to be performed repeatedly to make sure that the patient’s condition improves and the treatment is effective.When and how often the imaging should be performed depends on particular medical case. Doctors estimate the advantages and disadvantages of this procedure together with its risks, costs and other aspects.It is possible to ask the doctors about their reasons to perform some imaging and about other ways of it.
5. Can Reduce the Need for More Invasive Tests
Certain types of imaging allow doctors to examine internal organs without having to make incisions. The use of ultrasound, X-rays, CT scan, and MRI can provide information that can be obtained by using an invasive method only.For example, ultrasound may help to evaluate certain issues with soft tissue and perform certain procedures.Imaging is helpful for the doctors to know if certain procedures need to be done before performing the surgery. But imaging cannot substitute all invasive procedures. Sometimes a biopsy or any other procedure is needed. Imaging is significant as it helps the doctors to take appropriate actions..
6. Helps Monitor Certain Medical Conditions
Apart from being helpful in diagnosing various diseases, medical imaging is also valuable when it comes to monitoring certain illnesses.Depending on the illness, imaging can be recommended to monitor its development, examine any changes in a certain abnormality, and also assess the patient's reaction to the treatment. Depending on the illness, a certain kind of imaging and the frequency of the imaging can be chosen.
Some examples of such conditions to be monitored through imaging are:
- Certain types of fractures
- Some tumors and abnormalities
- Joint and spine conditions
- Organ-related illnesses
- Illnesses after treatment
Follow-up imaging must not be done routinely, but according to the needs of the patient. This is because certain types of scanning involve radiation if X-rays and CT scans are used.
7. Supports Coordinated Care Across Medical Teams
In some cases, patients require attention from more than one professional in the healthcare field. This is where imaging helps enhance the process of communicating between emergency doctors, primary care physicians, radiologists, and other medical specialists because of the visual information on the medical issue.A radiologist is a doctor who has knowledge in interpreting imaging and provides information that can be used in making diagnoses. The clinician uses the findings provided in imaging in consideration of the whole medical status of the patient.If there are medical images before that are relevant to the current medical issue, then they will play a key role in helping the clinicians interpret any change over the time. Patients can help in this regard by giving information regarding old scans and medical records.Communication is crucial especially in a situation where a patient is referred from emergency to follow-up consultations.
