In computed tomography (CT), the areas of the body to be examined are X-rayed, the rays are received
by detectors and converted into images by means of a high-performance computer. As a result, body
organs and areas can be imaged without overlay in a very short time.

The new spiral computer tomography even allows the display of entire body sections in a very short
time. So z. For example, the entire lung or the abdominal organs and the pelvis are examined while the
patient once holds the air. The focus of computed tomography is on the entire accident diagnostics,
including cranial and facial skulls, as well as the clarification of diseases of the lungs and abdominal
organs. The CT quickly provides a clear view of the abdominal cavity and chest. Bony changes and
fractures can be presented very accurately, as well as lung changes as well as inflammation, fibrosis and
tumors.

Additional information:

  • General patient information on CT examinations
    Is a CT painful?
  • The CT itself is completely painless. For the investigation, however, you have to stay still for up to 15
    seconds and hold your breath.

In some examinations, it may be necessary to put an infusion needle in your arm, which is as
uncomfortable as taking a blood sample.

  • What preparations are required?

As a rule, no preparation is necessary, except for some special examinations such as cardio-CT or virtual
colonoscopy.

If you regularly take medication, you should absolutely bring it with you, so that we can check whether it
could cause problems during the examination.

  • What can be examined with a CT?

Actually, all diseases that can be visualized. But one should check whether there are better or less
expensive procedures to come to a clear diagnosis.

  • What has to be brought to a CT?

Insured persons of the statutory health insurance must bring along their insurance card and a referral
from their doctor.

Insured persons of private health insurance should also bring a bank transfer slip. Based on the question
on the remittance slip, a more targeted examination can be carried out.

Information about Cardio-CT

In a computed tomography of the heart (cardio-CT), the heart is examined in a very fast computer
tomograph. The entire examination only takes about 6 seconds plus the preparation time (about 20
minutes). With this examination, bottlenecks in the coronary vessels, which can lead to a heart attack,
are detected and assessed.

Cardio-CT is a safe and fast method of examining the coronary arteries. This often allows a cardiac
catheterization to be avoided.

  • Is a cardiac CT scan painful?

The CT itself is completely painless. For the examination, however, you have to remain still for up to 10
seconds and hold your breath.

In all examinations it is necessary to put an infusion needle in your arm, which is about as unpleasant as
taking a blood sample.

  • What preparation is required?

On the morning of the examination day you should refrain from coffee and come as well as possible to
the investigation.

You take your medication normally. Please bring all medicines with you, because we need to check if
they could cause problems during the examination.

  • What must be brought to a cardio CT?

The cardio-CT is performed in cooperation with the heart-lung practice in Stade. This examination is not
a regular benefit of the statutory health insurance and must therefore be paid by the patient. However,
some private health insurance companies cover the costs. You should first check your insurance
conditions.

Insured persons of the statutory health insurance must also bring along their insurance card and a
referral from their doctor.

Insured persons of private health insurance should also bring a bank transfer slip. Based on the question
on the remittance slip, a more targeted examination can be carried out.

Virtual Colonoscopy / Kolography

This study is used to detect colon cancer and may replace a colonoscopy.

This examination is particularly suitable for patients in whom a normal colonoscopy can not be
completed or who do not want such an examination.

Colon cancer screening is an important task in colonoscopy, as colon cancer is one of the most common
cancers in Central Europe and accounts for 15% of all cancer deaths.

  • Is a virtual holographic painful?

For the examination, a small tube is inserted a few inches into the patient's anus. Subsequently, the
intestine can be unfolded with air. This is perceived by some patients as unpleasant, but not usually
painful.

The CT exam itself is completely painless. You have to lie still for about 15 seconds and hold your breath.

In all examinations, it is necessary to put an infusion needle in the arm, which is as unpleasant as taking
blood.

  • What preparation is required?

The virtual colography requires the same preparation as a regular colonoscopy. Two days before the
examination, the intestine must be cleaned. For this the patients receive special medicines.
Furthermore, only a small amount of solid food should be eaten.

Anyone taking medication should definitely bring it with them, because we need to check whether they
could cause problems in the investigation.

  • Can a virtual kolography always be performed?

Yes. However, patients should first discuss with their physician all options for early detection of
colorectal cancer.

  • What must be brought to a virtual Kolografie?

Documents about possible pre-existing conditions or operations are very helpful.

Insured persons of the statutory health insurance must bring along their insurance card and a referral
from their doctor.

Insured persons of a private health insurance should also bring a transfer slip, because then in this so
extensive investigation it is clearly defined, what exactly should be done.

bone Densitometry

A bone density measurement is used for osteoporosis diagnostics and for evaluation of the course of
therapy.

Osteoporosis is a disease characterized by loss of skeletal structure (loss of substance) and bone
calcification (decalcification). There is a mismatch between bone formation and degradation. The cause
is unknown. The development of the disease progresses for years before it subjectively causes the
affected person or – even worse – leads to fractures in more harmless accidents. Osteoporosis mainly
affects women.

Before a therapy, the diagnosis must be secured by measuring the bone density using X-rays or
ultrasound. Since the spinal column is the most frequently affected organ, only a measurement with X-
rays is possible here. Ultrasound does not have the appropriate permeability.

  • Is a bone density measurement painful?

The CT examination is completely painless. The patient only has to lie still for about 10 seconds.

  • How can I prepare?

As a rule, no preparation is necessary.

  • How accurate is the bone density measurement?

Bone densitometry, also called osteodensitometry, in a computed tomography (CT) machine is the
safest method. It displays the calcium content directly in milligrams per milliliter of bone mass. Because
of the exact bone density measurement, osteoporosis can not only be detected safely, but also
controlled during therapy. The radiation exposure of the CT examinations is minimal in today's modern
devices. The diagnostic benefit far surpasses theoretically possible damage.

  • What must be brought to a bone density measurement?

Insured persons of the statutory health insurance must bring along their insurance card and a referral
from their doctor.

Insured persons of private health insurance should also bring a bank transfer slip. Based on the question
on the remittance slip, a more targeted examination can be carried out.

Investigations: Magnetic Resonance Imaging (MRI)

Magnetic Resonance Imaging (MRI) provides sectional images of the body organs with high soft tissue
contrast and is characterized by a very accurate representation of the anatomical structures. MRI is also
called magnetic resonance imaging.

The MRI technique is based on an FM transmitter and a magnet that uniformly aligns the hydrogen
particles (protons) in the human body. The protons respond to high-frequency pulses (radio waves).
Special coils register the very weak echoes that are assembled into images in a high-performance
computer system. The stronger the magnet, the better the echo, the louder the sound, the faster a
detailed picture is created. Loud in this case is advantageous.

General patient information on MRI examinations

  • Is magnetic resonance imaging painful?

The MRI itself is completely painless and no X-rays are used. For the investigation, however, you have to
stay still for up to 30 minutes and hold your breath for a moment.
In some examinations it may be necessary to put an infusion needle in your arm, which is about as
uncomfortable as taking blood.

  • Can anyone be examined on MRI?

Patients with metallic implants, e.g. early models of pacemakers, metal splinters or artificial hip joints of
the first series may not be studied. Due to the strong magnetic forces of the MRI, there is a risk of
damage to the soft tissues adjacent to the implants.

Please be sure to let us know if you have metal on or in the body! (e.g., pacemakers, artificial joints,
piercings or shrapnel)

  • What preparation is required?

As a rule, no preparation is necessary. Exceptions exist with special investigations, z. A cardiac MRI or a
thin or large bowel MRI. Detailed information is available at the appointment.
If you are taking any medications you should definitely bring them with you so that we can check if they
could cause any problems during the examination.

Insured persons of the statutory health insurance must bring along their insurance card and a transfer
from their doctor.

Insured persons of private health insurance should also bring a bank transfer slip. Based on the question
on the remittance slip, a more targeted examination can be carried out.

Special Diagnostics: Breast MRI

In breast cancer diagnostics, magnetic resonance imaging (MRI) is used to obtain information about the
location and size of a tumor. For a better distinction between healthy and diseased tissue, a contrast
agent is often given, which represents the different blood flow in the tissues.

Magnetic resonance imaging is considered an important additional procedure in breast cancer
diagnostics. It is mainly used for the following questions:

– For the exclusion of very small, non-visible in mammography malignantly altered areas (lesions) in an
already known tumor;
– To control the development of tumors during therapy in addition to tactile findings and ultrasound;
– To distinguish between scar tissue after breast surgery and a new tumor (recurrence);
– In the investigation of women with breast implants,
– As an early detection test in high-risk patients due to familial breast and / or ovarian cancer.

Above all, breast MRI is an additional examination: because an MRI is very sensitive, many abnormalities
are shown. However, the changes detected by MRI do not necessarily have to be malignant, so they can
lead to unnecessary additional examinations. Only in young women with a hereditarily high cancer risk,
MRI is used as part of a special program for early detection, because at this age the mammography is
often not very meaningful because of the dense glandular tissue. In women with a high familial risk,
magnetic resonance imaging has a sensitivity, a detection rate in the case of a present malignant tumor,
of 90 percent. In combination with mammography, the rate is even 93 percent in this collective.
