CT (Computed Tomography) Machine/CAT Scan

Today’s healthcare environment is about offering new solutions to pressing needs. Humboldt County Memorial Hospital realizes that our providers want to do what is best for their patients, and so do we. For that reason, we want you to know that our facility offers CT imaging with new equipment & advanced technology.

Simple and fast, our CT machine is arguably one of the most valuable diagnostic imaging tools. Yet its capacity to improve the health of the world is far from tapped. It’s designed to support the widest variety of patients and applications. A CT scan can be used to visualize nearly all parts of the body and is often used to diagnose disease or injury as well as to plan medical, surgical or radiation treatment.

MRI- Magnetic Resonance Imaging

What is an MRI?

Magnetic resonance imaging—or MRI—uses a magnetic field, radio waves, and a computer to generate cross-sectional images of organs, soft tissues, bone, and virtually all other internal body structures. 

MRI does not use radiation. At Humboldt County Memorial Hospital, we recognize that having an MRI can be an anxiety provoking situation; therefore, we partner with Shared Medical Services and offer MRI’s services right here in Humboldt every Sunday afternoon/evening. The scanner utilized is a new wide-bore MRI scanner where patients can also select sound and lighting for a more relaxing yet personalized experience. Our knowledgeable, professional team will put you at ease and answer all of your questions before the exam.

What to expect?

Our technologist will take a brief medical history. If you are receiving IV contrast, you will be asked to lie down on the scanning table, and the contrast material will be injected into a vein in your arm. The table will then slide into the scanning area. During the test, the MRI will make a rapid tapping noise. Just relax and remain still.

You should plan 60–90 minutes of total appointment time. The scan typically takes 30–60 minutes, depending on the exam performed and whether contrast is required.

You may return to normal activities following your exam.

How do I prepare for an MRI scan?

Typically, no preparation is required before the exam. Some tests require an injection of IV contrast. For exams requiring contrast, a current creatinine test (within 45 days) may be required. The creatinine test is a blood draw to evaluate your kidney function and will normally be performed prior to the day of your exam. If fasting is necessary, your doctor will provide instructions. You will need to remove all jewelry, hair clips, and bobby pins. In addition, you will be asked to remove all clothing containing metal, including bras with metal enclosures and jeans with metal zippers, eyelets or buttons. A gown will be provided for you to wear.

What Contraindications do I need to be aware of?

If you are pregnant, have had an aneurysm clip, have had ear or eye prosthesis, or have a pacemaker, you may not be a candidate for an MRI. Because some tests require an injection of intravenous (IV) contrast, please inform your doctor if you have high blood pressure, diabetes, or have current or past renal insufficiency or acute vascular disease. You may or may not be able to receive contrast.

Low-Dose CT Lung Cancer Screenings & Calcium Scoring

These preventative screenings use low doses of radiation to make a series of detailed pictures making it easier to identify the cancer or blocked artery at an early stage so that it can be successfully treated. These scans are non-invasive and only take a few moments to complete.

This high resolution, low-contrast detect-ability scanner has many benefits, some include:

  • Up to 82% reduced dose.
  • Up to 100% better spatial resolution.
  • Up to 135% improved low-contrast detectability.

What is the cost of low-dose lung cancer screening and calcium scoring?

These screenings are self pay. All fees are due at time of service.

Low-Dose CT Lung Cancer Screening = $144
Calcium Scoring = $128
Low-Dose CT Lung Cancer Screening + Calcium Scoring = $195

Who should consider a calcium scoring?

Those at higher risk for developing coronary artery disease should discuss the potential benefits of cardiac calcium scoring with their physicians, who may recommend the exam.

Common CAD risk factors include:

  • Family history of CAD Diabetes
  • High LDL cholesterol Physical inactivity Obesity
  • Tobacco smoking

Who should consider a low-dose lung cancer screening?

Current and former smokers aged 55 and up are at greatest risk for developing lung cancer. All that's needed is a doctor's order.
