Radiology is one of the core medical specialties that utilizes medical imaging methods in the diagnosis and follow-up of diseases. Through advanced technologies such as X-ray, ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI), many structures ranging from internal organs and bone structures to soft tissues and the vascular system can be evaluated in detail. Radiology plays a critical role not only in the diagnostic process but also in treatment planning, monitoring disease progression and guiding interventional procedures.
What is Radiology?
Radiology is a branch of medicine that uses medical imaging techniques for the diagnosis of diseases, monitoring their progression and assisting in treatment planning. Internal structures of the body are evaluated in detail through radiological imaging. In this respect, radiology is a key field that provides data to almost all branches of modern medicine and occupies a central role in the diagnostic process.
The primary aim of radiology is to provide physicians with clear information about the location, condition and extent of a disease. Many conditions that cannot be detected through physical examination become visible through radiological imaging. Thus, the diagnostic process is accelerated and an appropriate treatment plan can be developed.
Radiology is not merely about image acquisition. The images obtained must be acquired using appropriate techniques and carefully evaluated by specialist physicians. Physicians who perform this evaluation are called radiology specialists. A radiology specialist examines the obtained images, reports the findings and guides the referring physician.
Radiology works in collaboration with almost all medical specialties today. It enables rapid decision-making in emergency situations, plays an important role in the follow-up of chronic diseases and contributes to the safe progression of the treatment process.

What Diseases Does Radiology Deal With?
Radiology is involved in the diagnosis and follow-up of many diseases affecting different organs and systems. It evaluates a wide range of areas rather than a single disease group, including the head and neck, chest, abdomen, musculoskeletal system, vasculature and many other regions. The most frequently evaluated disease groups in radiology are as follows:
Brain and nervous system diseases
- Stroke (paralysis) and brain hemorrhage suspicion
- Brain tumors and masses
- Aneurism and vein-related problems
- Head traumas
- Nervous system diseases like multiple sclerosis (MS)
- Headache, dizziness, neurogical finding investigations
Lung and thoracic diseases
- Pneumonia and lung infections
- Lung nodule and lung tumor suspicion
- Chronic lung diseases like COPD, emphysema
- Lung embolism (clotting) suspicion
- Chest traumas, rib fractures
Diseases of the intra-abdominal organs
- Liver fattening, cyst and masses
- Gallbladder stone and bile duct problems
- Pancreas inflammation and pancreas cysts
- Enlarged spleen, cysts
- Appendicitis suspicion
- Intestinal obstruction, inflammatory bowel disease suspicion
Kidney and urinary tract diseases
- Kidney stones and urinary tract stones
- Kidney cysts and kidney tumor suspicion
- Urinary tract obstruction
- Complication related to urinary tract infections
- Evaluation of mass/suspicious findings related to prostate and bladder
Musculoskeletal system diseases
- Fracture, dislocation, crack
- Sports injuries (ligament, meniscus, tendon problems)
- Lumbar and cervical hernia
- Joint calcification (osteoarthritis)
- Joint involvements in rheumatismal diseases
- Bone tumors and bone infections (osteomyelitis)
- Evaluation of spinal curvature and postural disorders
Vascular diseases
- Vascular obstructions and stenoses
- Varicose and vein problems
- Aneurism (bulge in vein)
- Clotting suspicion (thrombosis)
- Mapping of vascular structure before operation/treatment
Breast diseases
- Breast cyst and benign masses
- Breast cancer suspicion and screening
- Investigation of complaints like breast pain, palpable mass, discharge
Thyroid and neck region diseases
- Thyroid nodule
- Thyroid inflammation suspicion
- Lymph node enlargement
- Salivary gland problems
Gynecology
- Ovarian cyst
- Intra-uterine myoma suspicion
- Investigation of causes of pelvic pain
- Some evaluations related to pregnancy
What are Radiological Imaging Techniques?
Radiological imaging techniques are diagnostic methods that allow physicians to visualize the internal structures of the body. Through these methods, organs, bones, tissues and vessels can be examined and diseases can be diagnosed more accurately and rapidly. Imaging procedures are performed using X-rays, magnetic fields, sound waves or special materials. The choice of technique is determined by the patient's complaint and the area to be examined.
X-ray is one of the most commonly used and well-known imaging methods. It is obtained using X-rays and bone structures are visualized clearly. It is frequently preferred in the initial evaluation of fractures, dislocations and lung diseases. It is a rapid method that provides results in a short time.
Ultrasonography is a radiation-free imaging technique that uses sound waves. It is widely used in the evaluation of abdominal organs, the thyroid, the breast and pregnancy monitoring. Due to its safety, it can be easily applied in all age groups. Doppler ultrasonography is used to evaluate blood flow within blood vessels.
Computed tomography (CT) is a method that provides detailed cross-sectional images of the body. It is particularly used in emergency situations, trauma cases and for the detailed examination of internal organs. It provides more detailed images than X-ray but involves radiation exposure.
Magnetic resonance imaging (MRI) operates using strong magnetic fields and does not use radiation. It is highly effective in the evaluation of the brain, spine, joints and soft tissues. It provides detailed images, but the scanning time is longer compared to other methods.
Mammography is a specialized X-ray method used for imaging breast tissue. It plays an important role in the early diagnosis of breast cancer and is used for screening purposes. Bone densitometry helps assess the risk of osteoporosis by measuring bone mineral density.
Nuclear medicine imaging methods allow the evaluation of not only the structure of organs but also their function. Methods such as scintigraphy and PET are particularly used in cancer diagnosis and treatment monitoring. These techniques utilize low doses of radioactive substances. Each method serves a different need and is often used in a complementary manner.
What Treatments Are Applied By Radiology?
Radiology plays an important role not only in the diagnosis of diseases but also in treatment planning and follow-up. Radiology clearly identifies the location, size and extent of a disease before treatment is initiated. The obtained images help physicians make accurate decisions.
In some diseases, the effects of treatments are closely monitored using radiological imaging methods. These follow-up examinations help determine whether the treatment is effective, whether the disease is regressing or whether a new problem has developed. When necessary, the treatment plan is updated based on these images.
Radiology also helps in the early detection of potential risks during the treatment process. "In particular, in long-term or multi-stage treatments, regular imaging follow-ups enable the early detection of potential complications.
In some cases, radiology plays a role in planning special procedures that support treatment. These procedures are classified under interventional radiology, which is a separate subspecialty.
Does Radiology Check Cancer?
Radiology is one of the most commonly consulted departments in patients with suspected cancer. Radiology plays an important role in the investigation of cancer, the assessment of its spread and the monitoring of the treatment process. The first signs of cancer are often revealed through radiological imaging method.
Radiology also remains involved after a cancer diagnosis is made. Radiological examinations are used to determine whether the disease is confined to its original site or has spread to lymph nodes or other organs. This assessment helps in the appropriate selection of the treatment method.
Monitoring disease progression after treatment has begun is also among the responsibilities of radiology. Whether the tumor is shrinking, responding to treatment or whether a new problem has developed is monitored through regular imaging follow-ups. Thus, the treatment process can be adjusted at an early stage when necessary.
Which Patients Go To Radiology Department?
The radiology department is the unit where problem in the body are examined using imaging methods. For this reason, many patients with various complaints are referred to radiology by the relevant departments.
Patients who notice pain, swelling, limited movement or a mass anywhere in the body may be referred to radiology Imaging is also performed in injuries following falls, impacts or sports activities to assess fractures or tissue damage.
Radiological examinations may be requested in cases such as abdominal pain, suspected kidney or gallstones and urinary tract problems. Radiology is also consulted in cases of persistent cough, shortness of breath or suspected infection related to the lungs.
Patients presenting with symptoms such as headache, dizziness, numbness or sudden loss of strength are referred to radiology for evaluation of the brain and nervous system. In addition, radiology is also consulted for pregnancy follow-up, breast examinations, vascular diseases, monitoring of previously diagnosed conditions and screening purposes.
