Introduction
Head CT is a medical imaging technique that can clearly display the internal structures and tissues of the skull, and is of significant value in diagnosing various diseases. It can detect head injuries, cerebrovascular diseases, brain tumors, hydrocephalus, brain developmental abnormalities, infections, and more. Head CT is a crucial medical imaging technique that helps physicians promptly diagnose diseases and conditions.

Generally, head CT is a medical imaging technique that can clearly display the internal structures and tissues of the skull and is of significant value in diagnosing various diseases. It can detect head injuries, cerebrovascular diseases, brain tumors, hydrocephalus, brain developmental malformations, infections, and more. Detailed analysis is as follows:

1. Head Trauma

Head injuries caused by traffic accidents, falls, or other external impacts can be rapidly and accurately detected by head CT, including skull fractures, intracerebral hemorrhage, and subarachnoid hemorrhage. Head CT can clearly show fine fracture lines and bleeding areas, helping doctors assess injury severity and formulate treatment plans.

2. Cerebrovascular Diseases

Head CT can detect and assess strokes, including ischemic and hemorrhagic strokes, aneurysms, arteriovenous malformations, and other cerebrovascular diseases. Using head CT, doctors can quickly determine the location and severity of lesions, providing essential information for timely treatment and prevention of complications.

3. Brain Tumors

Head CT can display the location, size, and morphological characteristics of brain tumors, helping doctors evaluate the compression of surrounding brain tissues. Enhanced CT scans can further demonstrate the tumor's blood supply and boundaries, providing important information for developing surgical, radiotherapeutic, and chemotherapeutic treatment plans.

4. Hydrocephalus

Hydrocephalus caused by congenital factors or diseases such as meningitis and brain tumors, which lead to abnormal accumulation of cerebrospinal fluid in the ventricles and subarachnoid space, can be detected and assessed by head CT. It clearly shows the accumulation of cerebrospinal fluid, helping doctors determine the severity of hydrocephalus and formulate treatment plans.

5. Brain Developmental Malformations and Infections

Head CT can also detect certain congenital central nervous system malformations, such as anencephaly and microcephaly. Additionally, for central nervous system infections such as meningitis and brain abscesses, head CT can help doctors make diagnoses by showing abnormal density areas within the brain parenchyma, abscess formation, and thickening of the meninges.

Head CT is an important medical imaging technique that helps doctors promptly and accurately diagnose various intracranial diseases, providing essential evidence for developing treatment plans and assessing clinical outcomes.

What types of inflammation can be detected by a routine blood test?
In general, a routine blood test can help determine the presence of inflammatory conditions such as bacterial pneumonia, acute tonsillitis, acute gastroenteritis, pyelonephritis, and appendicitis. Additionally, routine blood tests may provide clues to other inflammatory diseases. However, final diagnosis requires comprehensive evaluation based on the patient's symptoms, medical history, and results from other diagnostic tests.

What measures are included in preventing hemolytic reactions?
In general, to prevent hemolytic reactions, strict measures should be taken, including verifying blood type and blood bag information, following proper procedures for blood storage and transportation, avoiding blood contamination, controlling the rate of transfusion, and assessing the patient's individual risk for hemolysis. Additionally, during transfusion, the patient's vital signs—such as body temperature, blood pressure, and urine output—should be closely monitored. If symptoms such as chills, back pain, or darkening of urine occur, immediate action should be taken.

What tests should be done initially for lymphoma?
In general, the initial evaluation of lymphoma involves ultrasound examination of lymph nodes, pathological biopsy, complete blood count, bone marrow aspiration, and CT scans. Additionally, depending on individual circumstances, patients with lymphoma may also undergo PET-CT or immunohistochemical testing. Patients should actively cooperate with their physicians during the diagnostic process, especially if any test results are abnormal.

Which medications should not be used in hemophilia?
In general, patients with hemophilia should avoid using medications such as enteric-coated aspirin tablets, ibuprofen sustained-release capsules, warfarin sodium tablets, clopidogrel hydrogen sulfate tablets, and dipyridamole tablets. They should also avoid strenuous exercise and trauma in daily life to reduce potential triggers for bleeding. If symptoms such as pain or fever occur, prompt medical attention is necessary, and safe medications should be selected under a doctor's guidance.

What are the acute causes of death in aplastic anemia?
In general, acute causes of death in aplastic anemia include severe intracranial hemorrhage, severe pulmonary infection, acute massive gastrointestinal bleeding, sepsis, and severe heart failure. Additionally, patients with aplastic anemia should be vigilant for complications such as urinary tract bleeding and retinal hemorrhage. Daily precautions include protecting against trauma, maintaining personal hygiene, and minimizing the risk of infection.

What are the commonly used anticoagulant drugs?
In general, commonly used clinical anticoagulant medications include warfarin sodium tablets, dabigatran etexilate capsules, rivaroxaban tablets, apixaban tablets, and fondaparinux sodium injection. When taking anticoagulant drugs, it is essential to strictly follow medical instructions; do not adjust the dosage or discontinue the medication on your own. During treatment, monitor carefully for any signs of bleeding, such as skin bruising, gum bleeding, or nosebleeds.

What tests are required before undergoing a bone marrow transplant?
In general, before undergoing a bone marrow transplant, patients need to complete evaluations including bone marrow examination, blood tests, imaging studies, cardiopulmonary function tests, and infection-related screenings. These assessments provide critical information for developing the transplant plan and evaluating potential risks. Additionally, some patients may require further tests such as thyroid function or immune function evaluations, depending on their specific clinical conditions.

What is the normal serum sodium concentration?
Under normal circumstances, the normal serum sodium concentration range is 135–145 mmol/L. In daily life, it is important to promptly replenish fluids and electrolytes after excessive sweating, vomiting, or diarrhea to prevent abnormal serum sodium levels. If symptoms such as fatigue, dizziness, or nausea occur, medical attention should be sought promptly to check serum sodium levels. Additionally, maintaining a balanced diet is essential.
