CT・MRI検査の英語表現完全ガイド：医療現場で役立つ実践フレーズ集

Technologist: Hello, I’m the CT technologist who will be performing your scan today. First, I will do the preparation of equipment and make sure everything is ready.
Patient: Thank you. What should I do now?

Technologist: Please lie down on the patient table. We will do patient positioning carefully to get clear images.
Patient: Is there anything else I need to know before the scan?

Technologist: If you are having a contrast-enhanced scan, we will insert an intravenous line for the contrast agent administration. The contrast injector will deliver the dye during the scan.
Patient: Will I feel anything during the injection?

Technologist: You might feel a warm sensation briefly. I will be monitoring the scan with real-time monitoring at the control console, and communicating with you throughout the procedure.
Patient: If I feel uncomfortable, what should I do?

Technologist: You can tell me anytime. Emergency protocols are in place, and I’m ready to press the emergency stop button if you need.

Technologist (after the scan): The scan is finished. Please wait here for observation and recovery if you had contrast material.
Patient: Thank you for your help!

Technologist: Good afternoon. I am your MRI technologist. Before we begin, we will do a safety screening to confirm no metal objects remain on you.
Patient: I’ve removed all my jewelry.

Technologist: Great. Now, I will help you lie on the patient table and apply the proper patient positioning and immobilization to keep you still.

Technologist: For your comfort, you will wear earplugs to protect against the loud noises during the scan.
Patient: How long will the scan take?

Technologist: The image acquisition will take about 45 minutes. If needed, a contrast agent injection might be performed during the scan.
Patient: Can I talk to you while inside?

Technologist: Yes, we will maintain communication through the intercom. Please stay as still as possible.
Patient: Understood. Thank you.

Technologist (after the scan):
All done. You may remove the earplugs. The radiologist will review your images and your referring doctor will explain the radiologist’s report in the next consultation.

Comprehensive Guide to CT and MRI Examinations

1. What is a CT scan?

A CT scan (/ˌsiːˈtiː skæn/) is a diagnostic test that uses X-rays to create cross-sectional images of the body. It is particularly useful for visualizing bones, organs, and detecting internal injuries.

Example:
The doctor ordered a CT scan to check for any internal injuries.

2. What is an MRI (Magnetic Resonance Imaging)?

MRI (/ˌɛm ɑːr ˈaɪ/) is a test that uses powerful magnets and radio waves to create detailed images of organs and tissues inside the body, without using radiation.

Example:
The patient underwent an MRI to assess brain abnormalities.

3. Preparing for the Examination

A. Making an Appointment

Before the scan, you must make an appointment (/əˈpɔɪntmənt/) at the imaging facility.

Example:
Please make an appointment for the CT scan at least one week in advance.

B. Fasting and Dietary Instructions

Depending on the test, you may be required to undergo fasting (/ˈfæstɪŋ/) for a few hours beforehand.

Example:
You may be asked to fast for four hours before the CT scan.

C. Screening and Safety Checks

For MRI, you must complete a screening questionnaire (/ˈskriːnɪŋ ˈkwɛstʃəˌnɛər/) to check for metal implants or devices.

Example:
Before the MRI, you must complete a screening questionnaire regarding metal implants.

Removal of metal objects (/rɪˈmuːvəl əv ˈmɛtl ˈɒbdʒɪkts/) is also required.

Example:
Please remove all metal objects before entering the MRI room.

4. On the Day of Examination

A. Check-in

Arrive at the facility early for check-in (/ˈtʃɛkˌɪn/), fill out forms, and receive instructions.

Example:
Please arrive early for check-in and complete the necessary paperwork.

B. Preparation of Equipment and Preparation Area

The CT technologist or MRI technologist will carry out preparation of equipment (/ˌprɛpəˈreɪʃən əv ɪˈkwɪpmənt/) and guide you to the preparation area (/ˌprɛpəˈreɪʃən ˈɛəriə/).

Example:
The CT technologist explained the procedure before the scan.
You will wait in the preparation area before the scan.

C. Patient Positioning and Comfort

You will be helped onto the patient table (/ˈpeɪʃənt ˈteɪbl/, /ɪɡˌzæməˈneɪʃən ˈteɪbl/) and undergo patient positioning (/ˈpeɪʃənt pəˈzɪʃənɪŋ/) and (for MRI) patient positioning and immobilization.

Example:
Please lie down on the patient table. Accurate patient positioning is essential for quality images.

A comfortable headrest (/ˈhɛdˌrɛst/) or head immobilizer may be used.

Example:
The patient’s head was supported by a comfortable headrest.

D. Protection from Noise (MRI)

You will wear earplugs (/ˈɪərˌplʌɡz/) or headphones for noise protection during the MRI.

Example:
You will wear earplugs to protect your ears from the loud noises.

E. Contrast Agent Administration / Injection

Some scans require a contrast agent (/ˈkɒntræst ˈeɪdʒənt/), administered by contrast injection or through a contrast injector.

Example:
A contrast agent will be injected to highlight your blood vessels.
The nurse prepared the contrast injector before administering the dye.

An intravenous line setup (/ˌɪntrəˈviːnəs laɪn ˈsɛtʌp/) is performed if contrast is needed.

F. Scan Protocol Selection and Image Acquisition

The radiologist will decide the scan protocol selection (/skæn ˈproʊtəˌkɒl səˈlɛkʃən/), and the technologist will handle image acquisition (/ˈɪmɪdʒ ˌækwɪˈzɪʃən/) and quality check.

Example:
The radiologist guided the technologist in scan protocol selection.
The image acquisition usually takes 10 to 30 minutes.

G. During the Exam

The technologist monitors the scan using the control console (/kənˈtroʊl ˈkɒnsəʊl/) and provides communication with the patient (/kəˌmjuːnɪˈkeɪʃən wɪð ˈpeɪʃənt/) or (for MRI) communication through intercom.

Example:
I will be monitoring the scan with real-time monitoring at the control console, and communicating with you throughout the procedure.

If needed, an emergency stop button is available for your safety.

Example:
The technologist is ready to press the emergency stop button if the patient feels unwell.

5. Equipment Used

• CT scanner (/siː-tiː ˈskænər/)
• MRI machine or MRI scanner (/ˌɛm-ɑːr-ˈaɪ məˈʃiːn/)
• Coils for MRI (/kɔɪlz/)
• Lead apron for radiation protection in CT (/liːd ˈeɪprən/)

Example:
The MRI machine produces detailed images of soft tissues.
Staff wear lead aprons during CT procedures to minimize radiation exposure.

6. After the Examination

Observation and Recovery

If a contrast agent was used, you may be monitored for a short while for observation and recovery(/ˌɒbzərˈveɪʃən ænd rɪˈkʌvəri/).

Example:
You may be asked to stay for 30 minutes for observation and recovery.

For MRI, you can usually leave immediately after your exam, unless post-contrast observation is required.

7. Results and Next Steps

Radiologist’s Report

A radiologist’s report is created by analyzing your images.

Example:
The MRI images will be reviewed by the radiologist and a report sent to your doctor.

Explanation of Results

Your doctor will provide an explanation of results during your next visit or consultation.

Example:
You will receive an explanation of results during your follow-up appointment.
