MRI or CT scan

Please tell me what kind of examination is better in case of head injury - an MRI or CT scan. I have hit my head in June this year, and now I feel a discomfort at the site of the injury sometimes (there in no acute pain)?

CT has advantages in the visualization of bone structures. MRI is better for soft structures imaging, including the brain substance. According to the description, the intracranial structures damage is unlikely. Why CT or MRI? An ultrasound of soft tissues in the area of injury is also applicable. The pain in the scull can also be associated with vessel, for example, cranial arteritis, or lymphadenitis, or muscle/enthesis, and then you might need certain blood tests. And maybe these tests are not required. I would recommend you to see the doctor and let him assess the case; he will take a decision concerning following examination as a result of consultation.
