Sample Pre-Mammography Questionnaire
Before receiving a mammogram, women are usually required to fill out detailed questionnaires. Information pertaining to a personal and family medical history, previous mammograms and other breast imaging tests, etc.
How Can I Prepare For My Mammogram?
Preparation for mammography requires a few simple steps from the patient and mostly requires good communication with the technologist who will perform the mammogram and a good knowledge of your previous mammogram history.
Diagnostic Mammography
Notice: Revised breast cancer screening guidelines issued in November 2009. What is Diagnostic Mammography? Diagnostic mammography is an x-ray exam of the breasts that is performed in order to evaluate a breast complaint or abnormality detected by physical exam or routine screening mammography.
The Case for Mammography: What One Flawed Study and Critics of the Exam Don't Address
In their September 20, 2000 issue, the Journal of the National Cancer Institute published the most recent results of a highly controversial study.
Mammogram Report
Notice: Revised breast cancer screening guidelines issued in November 2009. A mammogram report is a key component of the breast cancer diagnostic process.
Mammogram Interpretation: Categories and the ACR/BI-RADS
The American College of Radiology (ACR) has established the Breast Imaging Reporting and Database System (BI-RADSTM) to guide the breast cancer diagnostic routine.
Digital Mammography
One of the most recent advances in x-ray mammography is digital mammography. Digital (computerized) mammography is similar to standard mammography in that x-rays are used to produce detailed images of the breast.
Choosing a Mammography Facility
Notice: Revised breast cancer screening guidelines issued in November 2009. As patients and medical consumers, women have the right to inquire about the facilities and qualifications of the physicians performing any medical service or imaging exam.
Thermography / Computerized Thermal Imaging
What is Thermography? Thermography (also called thermal imaging or infrared imaging) was approved by the U.S. Food and Drug Administration (FDA) in 1982 as a supplement to mammography in helping to detect breast cancer.
Why is Nuclear Medicine Performed?
Nuclear medicine imaging (also called radionuclide scanning) shows not only the anatomy (structure) of an organ or body part, but the function of the organ as well. This functional information can show if the organ is working properly.
PET Scanning and SPECT Scanning
Positron Emission Tomography (PET) scanning is a type of nuclear medicine scanning that involves cross sectional data acquisition and reconstruction much like Computed Tomography (CT) scanning.
How Does Nuclear Medicine Work?
Nuclear medicine studies were first performed in the 1950s using special devices called "gamma cameras." Nuclear medicine studies require the oral or intravenous introduction of very low-level radioactive chemicals (called radionuclides, radiopharmaceuticals or radiotracers) into the body.
Nuclear Medicine Imaging (NM)
Nuclear medicine imaging (also called radionuclide scanning) is an effective diagnostic tool because it shows not only the anatomy (structure) of an organ or body part, but the function of the organ as well.
Who are the Professionals in Nuclear Medicine?
Like all medical imaging examinations and therapy sessions, nuclear medicine imaging and therapy requires a team effort. The nuclear medicine patient care team is headed by a nuclear medicine physician. Other team members include nuclear medicine technologists and physicists.
Clinical Uses of Nuclear Medicine
Nuclear medicine is used mainly to allow visualization of organs and regions within organs that cannot be seen on conventional x-ray images. Space occupying lesions (injury or abnormality), especially tumors, may stand out on nuclear medicine images.
History of Nuclear Medicine
Nuclear medicine began more than 50 years ago and is now a vital medical specialty for both diagnosis and therapy of serious disease.
Clinical Uses of Nuclear Medicine
In a stress thallium study, two data acquisitions are performed during a stress thallium study. First, the patient is vigorously exercised on a treadmill or stationary bicycle to elevate cardiovascular activity and "stress" the heart. This is followed immediately by a nuclear medicine examination.
Clinical Uses of Nuclear Medicine
Nuclear medicine is used mainly to allow visualization of organs and regions within organs that cannot be seen on conventional x-ray images. Space occupying lesions (injury or abnormality), especially tumors, may stand out on nuclear medicine images.
Diagnostic & Therapeutic Procedures
This section discusses a variety of diagnostic and therapeutic procedures, such as angiography, CAT scan, MRI scan, nuclear medicine, radiotherapy, x-ray imaging, ultrasound, Pap smear, and more.

Frequently Asked Questions About Mammography and Breast Cancer
What is a Baseline Mammogram? A baseline mammogram is the set of images used as the basis for comparison in later tests. It is usually a patient's first screening mammogram, unless those films are unavailable. Patients should always try to keep track or when and where they have had each mammogram.
General Information on Mammography
Minimizing Pain and Discomfort During Mammography The benefit of mammography in helping to detect breast cancer early clearly outweighs the temporary discomfort of the exam. However, some women do find mammograms to be uncomfortable and sometimes painful.
Frequently Asked Questions About Mammography and Breast Cancer
Why Aren't Mammograms Recommended for Women Under Age 40? Physicians do not generally recommend that women under age 40 receive annual screening mammograms because younger women tend to have more dense breast tissue.

Endoscopy Procedure - What is Endoscopy
What is Endoscopy and Why is it Performed? Endoscopy allows physicians to peer through the body's passageways. Endoscopy is the examination and inspection of the interior of body organs, joints or cavities through an endoscope.
X-ray Safety and Risks
X-rays are a type of electromagnetic radiation, are invisible and create no sensation when they pass through the body. Modern x-ray techniques only use of fraction of the x-ray dose required in the early days of radiology.
How does x-ray imaging work?
X-rays are also referred to as radiographs or roentgenograms (after W.C. Roentgen). Conventional x-ray imaging has evolved over the past 100 years, but the basic principal is still the same as in 1895.
