Radiographic Technique II AMRR 221 Dr. Elbagir Hamza Manssor, Ph.D. Ass. Professor Department of Applied Radiological Sciences College of Applied Medical Sciences Jeddah University. Lec (10) Mammography Mammography is a specific type of imaging that uses a low-dose x-ray system for examination of the breasts. Common uses of the procedure: Diagnostic mammography is used to evaluate a patient with abnormal clinical findings, such as a breast lump or lumps that have been found by the woman or her doctor. ‫ﺴﺘﺨﺪم‬J ‫ﺮ‬LM‫ع ﻣﻌﻴﻦ ﻣﻦ اﻟﺘﺼ‬M‫ﺮ اﻟﺸﻌﺎﻋﻲ ﻟﻠﺜﺪي ﻫﻮ ﻧ‬LM‫اﻟﺘﺼ‬ .‫ﺠﺮﻋﺔ ﻣﻨﺨﻔﻀﺔ ﻟﻔﺤﺺ اﻟﺜﺪﻳﻴﻦ‬h ‫ﺔ‬i‫ﻨ‬j‫ﻧﻈﺎم اﻷﺷﻌﺔ اﻟﺴ‬ :‫اﻻﺳﺘﺨﺪاﻣﺎت اﻟﺸﺎﺋﻌﺔ ﻟﻺﺟﺮاء‬ ‫ﻢ‬i‫ﺼﻲ ﻟﺘﻘﻴ‬i‫ﺸﺨ‬x‫ﺮ اﻟﺸﻌﺎﻋﻲ ﻟﻠﺜﺪي اﻟ‬LM‫ﺴﺘﺨﺪم اﻟﺘﺼ‬J ‫ ﻣﺜﻞ ﻛﺘﻠﺔ‬،‫ﺔ‬i‫ﻌ‬i‫ﺔ ﻏﻴﺮ ﻃﺒ‬L•L‫ﺾ اﻟﺬي ﻟﺪ‚ﻪ ﻧﺘﺎﺋﺞ ﺳﺮ‬L•‫اﻟﻤ‬ .‫ﺒﻬﺎ‬j‫ﺘﻞ اﻟﺘﻲ ﻋﺜﺮت ﻋﻠﻴﻬﺎ اﻟﻤﺮأة أو ﻃﺒ‬Š‫اﻟﺜﺪي أو اﻟ‬ Mammography equipment: • A mammography unit is a rectangular box that houses the tube in which x-rays are produced. • The unit is dedicated equipment because it is used exclusively for x-ray exam of the breast, with special accessories that allow only the breast to be exposed to the x-rays. • Attached to the unit is a device that holds and compresses the breast and positions it so images can be obtained at different angles. :‫ﺮ اﻟﺸﻌﺎﻋﻲ ﻟﻠﺜﺪي‬VW‫ﻣﻌﺪات اﻟﺘﺼ‬ .‫ﻀﻢ اﻷﻧﺒﻮب اﻟﺬي ﻳﺘﻢ ﻓ]ﻪ إﻧﺘﺎج اﻷﺷﻌﺔ اﻟﺴ_ﻨ]ﺔ‬o ‫ﺮ اﻟﺸﻌﺎﻋﻲ ﻟﻠﺜﺪي ﻫﻲ ﺻﻨﺪوق ﻣﺴﺘﻄ]ﻞ‬VW‫وﺣﺪة اﻟﺘﺼ‬ ‫ ﻣﻊ ﻣﻠﺤﻘﺎت‬،‫ﺎ ﻟﻔﺤﺺ اﻟﺜﺪي |ﺎﻷﺷﻌﺔ اﻟﺴ_ﻨ]ﺔ‬V‫اﻟﻮﺣﺪة ﻋ…ﺎرة ﻋﻦ ﻣﻌﺪات ﻣﺨﺼﺼﺔ ﻷﻧﻬﺎ •ﺴﺘﺨﺪم ﺣﺼﺮ‬ .‫ﺧﺎﺻﺔ •ﺴﻤﺢ ﻓﻘﻂ ﻟﻠﺜﺪي |ﺎﻟﺘﻌﺮض ﻟﻸﺷﻌﺔ اﻟﺴ_ﻨ]ﺔ‬ .‫ﺎ ﻣﺨﺘﻠﻔﺔ‬o‫ﻤﻜﻦ اﻟﺤﺼﻮل ﻋﻠﻰ اﻟﺼﻮر ﺑﺰوا‬o ‫ﻀﻌﻪ |ﺤ]ﺚ‬V‫ﻀﻐﻄﻪ و‬V‫ﺤﻤﻞ اﻟﺜﺪي و‬o ‫ﻣﺮﻓﻖ |ﺎﻟﻮﺣﺪة ﺟﻬﺎز‬ Breast compression is necessary in order to: • Press out the breast thickness so that all of the tissue can be visualized; • Spread out the tissue so that small abnormalities won't be obscured by overlying breast tissue; • Allow the use of a lower x-ray dose since a thinner amount of breast tissue is being imaged; • Hold the breast still in order to eliminate blurring of the image caused by motion; • Reduce x-ray scatter to increase sharpness of picture. :‫ﺿﻐﻂ اﻟﺜﺪي ﺿﺮوري ﻣﻦ أﺟﻞ‬ ‫ﺴﺠﺔ؛‬œ‫ﻤﻜﻦ ﺗﺼﻮر ﺟﻤﻴﻊ اﻷ‬o ‫اﺿﻐﻂ ﻋﻠﻰ ﺳﻤﻚ اﻟﺜﺪي ﺣﺘﻰ‬ ‫ﺴﺠﺔ اﻟﺜﺪي اﻟﻤﺘﻔﻮﻗﺔ؛‬œ‫ﻖ أ‬V¢‫ﺸﻮﻫﺎت اﻟﺼﻐﻴﺮة ﻋﻦ ﻃ‬¤‫ﺴﺠﺔ ﺣﺘﻰ ﻻ ﻳﺘﻢ ﺣﺠﺐ اﻟ‬œ‫ﺸﺮ اﻷ‬œ‫ا‬ ‫ﺴﺠﺔ اﻟﺜﺪي؛‬œ‫ﺮ §ﻤ]ﺔ أرق ﻣﻦ أ‬VW‫اﻟﺴﻤﺎح |ﺎﺳﺘﺨﺪام ﺟﺮﻋﺔ أﻗﻞ ﻣﻦ اﻷﺷﻌﺔ اﻟﺴ_ﻨ]ﺔ ﺣ]ﺚ ﻳﺘﻢ ﺗﺼ‬ ‫أﻣﺴﻚ اﻟﺜﺪي ﺳﺎ¬ﻨﺎ ﻣﻦ أﺟﻞ اﻟﻘﻀﺎء ﻋﻠﻰ ﻃﻤﺲ اﻟﺼﻮرة اﻟﻨﺎﺟﻢ ﻋﻦ اﻟﺤﺮﻛﺔ؛‬ .‫ﺎدة ﺣﺪة اﻟﺼﻮرة‬V®‫ﺖ اﻷﺷﻌﺔ اﻟﺴ_ﻨ]ﺔ ﻟ‬¤‫ﻗﻠﻞ ﻣﻦ •ﺸ‬ Preparation for a mammogram: • Remove deodorant, talcum powder, or lotion under the arms or on breasts on the day of the exam.

Breast size varies from one individual to another and even in the same woman, depending on her age and the influence of various hormones. The usual breast extends from the anterior portion of the second rib down to the sixth or seventh rib and from the lateral border of the sternum well into the axilla. ‫ﺔ‬i‫ﺔ أو ﺛﺪﻳﻴﻦ ﻫﻲ ﺳﻤﺎﺣﺔ ﻣﺨﺮوﻃ‬i‫ﻞ ﻏﺪد اﻟﺜﺪﻳ‬œ ،‫ﺎﻟﻐﺔ‬ž‫ﻓﻲ اﻷﻧﺜﻰ اﻟ‬ .‫ﺔ‬i¡‫ﺔ واﻟﺠﺎﻧ‬i‫ﺔ ﺗﻘﻊ ﻋﻠﻰ ﺟﺪران اﻟﺼﺪر اﻷﻣﺎﻣ‬L‫أو ﻧﺼﻒ ﻛﺮو‬ ،‫‚ﺨﺘﻠﻒ ﺣﺠﻢ اﻟﺜﺪي ﻣﻦ ﻓﺮد إﻟﻰ آﺧﺮ وﺣﺘﻰ ﻓﻲ ﻧﻔﺲ اﻟﻤﺮأة‬ .‫اﻋﺘﻤﺎدا ﻋﻠﻰ ﻋﻤﺮﻫﺎ وﺗﺄﺛﻴﺮ اﻟﻬﺮﻣﻮﻧﺎت اﻟﻤﺨﺘﻠﻔﺔ‬ ‫‚ﻤﺘﺪ اﻟﺜﺪي اﻟﻤﻌﺘﺎد ﻣﻦ اﻟﺠﺰء اﻷﻣﺎﻣﻲ ﻣﻦ اﻟﻀﻠﻊ اﻟﺜﺎﻧﻲ إﻟﻰ اﻟﻀﻠﻊ‬ .‫ﻄﻴﻦ‬h‫ﺔ ﻟﺒﺌﺮ اﻟﻘﺺ إﻟﻰ اﻹ‬i¡‫اﻟﺴﺎدس أو اﻟﺴﺎﺑﻊ وﻣﻦ اﻟﺤﺪود اﻟﺠﺎﻧ‬ • The surface anatomy includes the nipple, a small projection co taining a collection of duct openings from the secretory glands within the breast tissue. 2nd rib • The pigmented area surrounding the nipple is termed the areola, a circular area of different color surrounding a central point. • The junction of the inferior part of the breast with the anterior chest wall is called the inframammary crease. • The axillary tail is a band of tissue that wraps around the pectoral muscle late ally (Fig. 5). .‫ﺔ داﺧﻞ أ´ﺴﺠﺔ اﻟﺜﺪي‬L‫ وﻫﻮ إﺳﻘﺎط ﺻﻐﻴﺮ ‚ﺤﺘﻮي ﻋﻠﻰ ﻣﺠﻤﻮﻋﺔ ﻣﻦ ﻓﺘﺤﺎت اﻟﻘﻨﻮات ﻣﻦ اﻟﻐﺪد اﻹﻓﺮاز‬،‫ ــﺢ اﻟﺴﻄﺤﻲ اﻟﺤﻠﻤﺔ‬L‫ﺸﺮ‬x‫ﺸﻤﻞ اﻟ‬J .‫ﺔ‬Lº‫ﻂ ﺑﻨﻘﻄﺔ ﻣﺮﻛ‬i‫ﺔ ذات ﻟﻮن ﻣﺨﺘﻠﻒ ﺗﺤ‬L•‫ وﻫﻲ ﻣﻨﻄﻘﺔ داﺋ‬،‫ﺎﻟﺤﻠﻤﺔ اﻟﻬﺎﻟﺔ‬h ‫ﻄﺔ‬i‫ﻐﺔ اﻟﻤﺤ‬ž‫½ﺴﻤﻰ اﻟﻤﻨﻄﻘﺔ اﻟﻤﺼﻄ‬ . .‫ﺪ ﺗﺤﺖ اﻟﺜﺪي‬i‫ﺎﻟﺘﺠﺎﻋ‬h ‫ﺠﺪار اﻟﺼﺪر اﻷﻣﺎﻣﻲ‬h ‫ﺴﻤﻰ ﺗﻘﺎﻃﻊ اﻟﺠﺰء اﻟﺴﻔﻠﻲ ﻣﻦ اﻟﺜﺪي‬J .(5 .‫ﺔ ﻓﻲ وﻗﺖ ﻻﺣﻖ )اﻟﺸ¿ﻞ‬L‫ﻂ ﻣﻦ اﻷ´ﺴﺠﺔ اﻟﺘﻲ ﺗﻠﺘﻒ ﺣﻮل اﻟﻌﻀﻠﺔ اﻟﺼﺪر‬L‫ﻄﻲ ﻫﻮ ﺷﺮ‬h‫اﻟﺬ‚ﻞ اﻹ‬ Fig. 5.

The quadrant system, shown in Fig. 7a, is easiest to use. Four quadrants can be described by using the nipple as the center. These quadrants are the UOQ (upper outer quadrant), the UIQ (upper inner quadrant), the LOQ (lower outer quadrant), and the LIQ (lower inner quadrant). A second clock system method, shown on the right in Fig. 7b, compares the surface of the breast to the face of a clock. A problem with the clock method arises when a medial or lateral portion of either breast is described. What is described at 3 o'clock in the right breast has to be described at 9 o'clock in the left breast. .‫ﻃﺮق اﻟﺘﻮﻃﻴﻦ‬ .‫ﻘﺘﻴﻦ ﻟﺘﻘﺴ]ﻢ اﻟﺜﺪي إﻟﻰ ﻣﻨﺎﻃﻖ أﺻﻐﺮ ﻷﻏﺮاض اﻟﺘﻮﻃﻴﻦ‬V¢‫ﺸﻴﻊ اﺳﺘﺨﺪام ﻃ‬Î .‫ أﺳﻬﻞ ﻓﻲ اﻻﺳﺘﺨﺪام‬،‫أ‬7 ‫ﻞ‬Â‫ اﻟﻤﻮﺿﺢ ﻓﻲ اﻟﺸ‬،‫ﺎﻋﻲ‬Å¢‫اﻟﻨﻈﺎم اﻟ‬ .‫ﺎع |ﺎﺳﺘﺨﺪام اﻟﺤﻠﻤﺔ §ﻤﺮﻛﺰ‬Å‫ﻌﺔ أر‬Å‫ﻤﻜﻦ وﺻﻒ أر‬o ‫ــﻊ اﻟﺨﺎرﺟﻲ‬Å¢‫ )اﻟ‬LOQ‫ و‬،(‫ــﻊ اﻟﺪاﺧﻠﻲ اﻟﻌﻠﻮي‬Å¢‫ )اﻟ‬UIQ‫ و‬،(‫ــﻊ اﻟﺨﺎرﺟﻲ اﻟﻌﻠﻮي‬Å¢‫ )اﻟ‬UOQ ‫ﺎع ﻫﻲ‬Å‫ﻫﺬە اﻷر‬ .(‫ــﻊ اﻟﺪاﺧﻠﻲ اﻟﺴﻔﻠﻲ‬Å¢‫ )اﻟ‬LIQ‫ و‬،(‫اﻟﺴﻔﻠﻲ‬ .‫ ﺳﻄﺢ اﻟﺜﺪي ﺑﻮﺟﻪ اﻟﺴﺎﻋﺔ‬،‫ب‬7 ‫ﻞ‬Â‫ اﻟﻤﻮﺿﺤﺔ ﻋﻠﻰ اﻟ]ﻤﻴﻦ ﻓﻲ اﻟﺸ‬،‫ﻘﺔ ﻧﻈﺎم اﻟﺴﺎﻋﺔ اﻟﺜﺎﻧ]ﺔ‬V¢‫ﺗﻘﺎرن ﻃ‬ .‫ﺴﻲ أو ﺟﺎﻧﺒﻲ ﻣﻦ أي ﻣﻦ اﻟﺜﺪﻳﻴﻦ‬œ‫ﻘﺔ اﻟﺴﺎﻋﺔ ﻋﻨﺪ وﺻﻒ ﺟﺰء إ‬V¢‫ﻠﺔ ﻓﻲ ﻃ‬Â‫ﺸﺄ ﻣﺸ‬Æ‫ﺗ‬ .‫ﺴﺮ‬Î‫ ﻓﻲ اﻟﺜﺪي اﻷ‬9 ‫ﻤﻦ ﻓﻲ اﻟﺴﺎﻋﺔ‬o‫ ﻓﻲ اﻟﺜﺪي اﻷ‬3 ‫ﺠﺐ وﺻﻒ ﻣﺎ ﻳﺘﻢ وﺻﻔﻪ ﻓﻲ اﻟﺴﺎﻋﺔ‬o Fig.7 a.

Breast sagittal section • A sagittal section through a mature breast is illustrated in Fig. 8, showing the relationship of the mammary gland to the underlying structures of the chest wall. • On this drawing the inframammary crease is at the level of the sixth rib, but a great deal of variation does exist among individuals. • The large pectoralis major muscle is seen overlying the bony thorax. • A sheet of fibrous tissue surrounds the breast below the skin surface. • A similar sheet of tissue covers the pectoralis major muscle. • These two fibrous sheets connect in an area termed the retromammary space. • This retromammary space must be demonstrated on at least one projection during the radiographic study of the mammary gland. Because the connections within the retromammary space are fairly loose, the normal breast exhibits considerable mobility on the chest wall. ‫ـ ــﺢ اﻟﻘﺴﻢ اﻟﺴﺎﻣﺠﻲ‬V‫•ﺸﺮ‬ ‫ﺪل ﻋﻠﻰ ﻋﻼﻗﺔ اﻟﻐﺪة اﻟﺜﺪﻳ]ﺔ |ﺎﻟﻬ]ﺎ¶ﻞ اﻷﺳﺎﺳ]ﺔ ﻟﺠﺪار‬o ‫ ﻣﻤﺎ‬،‫ ﻗﺴﻢ اﻟﺴﻬﻢ ﻣﻦ ﺧﻼل اﻟﺜﺪي اﻟﻨﺎﺿﺞ‬8 ‫ﻞ‬Â‫ﻳﻮﺿﺢ اﻟﺸ‬ .‫اﻟﺼﺪر‬ ‫ﻦ ﻳﻮﺟﺪ ﻗﺪر ﻛﺒﻴﺮ ﻣﻦ اﻻﺧﺘﻼف ﺑﻴﻦ‬Û‫ وﻟ‬،‫ﻜﻮن اﻟﺘﺠﻌﺪ ﺗﺤﺖ اﻟﺜﺪي ﻋﻠﻰ ﻣﺴﺘﻮى اﻟﻀﻠﻊ اﻟﺴﺎدس‬o ،‫ﻓﻲ ﻫﺬا اﻟﺮﺳﻢ‬ .‫اﻷﻓﺮاد‬ .‫ﺒﻴﺮة ﻓﻮق اﻟﺼﺪر اﻟﻌﻈﻤﻲ‬Û‫ﺴ]ﺔ اﻟ‬Þ‫ﺔ اﻟﺮﺋ‬V‫ﺷﻮﻫﺪت اﻟﻌﻀﻼت اﻟﺼﺪر‬ .‫ﺴﺠﺔ اﻟﻠ]ﻔ]ﺔ |ﺎﻟﺜﺪي ﺗﺤﺖ ﺳﻄﺢ اﻟﺠﻠﺪ‬œ‫ﺗﺤ]ﻂ ورﻗﺔ ﻣﻦ اﻷ‬ .‫ﺴ]ﺔ‬Þ‫ﺔ اﻟﺮﺋ‬V‫ﺴﺠﺔ اﻟﻌﻀﻼت اﻟﺼﺪر‬œ‫ﺗﻐﻄﻲ ورﻗﺔ ﻣﻤﺎﺛﻠﺔ ﻣﻦ اﻷ‬ .‫ﺗﺘﺼﻞ ﻫﺎﺗﺎن اﻟﺼﻔﺤﺘﺎن اﻟﻠ]ﻔﻴﺘﺎن ﻓﻲ ﻣﻨﻄﻘﺔ •ﺴﻤﻰ اﻟﻔﻀﺎء اﻟﺨﻠﻔﻲ ﻟﻠﺜﺪي‬ ‫ ﻧﻈﺮا ﻷن‬.‫ﺠﺐ إﻇﻬﺎر ﻫﺬا اﻟﻔﻀﺎء ﺧﻠﻒ اﻟﺜﺪي ﻋﻠﻰ إﺳﻘﺎط واﺣﺪ ﻋﻠﻰ اﻷﻗﻞ أﺛﻨﺎء اﻟﺪراﺳﺔ اﻟﺸﻌﺎﻋ]ﺔ ﻟﻠﻐﺪة اﻟﺜﺪﻳ]ﺔ‬o .‫ﻈﻬﺮ ﺣﺮﻛﺔ ﻛﺒﻴﺮة ﻋﻠﻰ ﺟﺪار اﻟﺼﺪر‬o ‫ ﻓﺈن اﻟﺜﺪي اﻟﻄﺒ]ﻌﻲ‬،‫اﻻﺗﺼﺎﻻت داﺧﻞ اﻟﻔﻀﺎء ﺧﻠﻒ اﻟﺜﺪي ﻓﻀﻔﺎﺿﺔ إﻟﻰ ﺣﺪ ﻣﺎ‬ Skin Glandular tissue • The relative position of glandular tissue versus adipose (fatty) tissue is illustrated in Fig. 9. The central portion of the breast is primarily glandular tissue. • Varying amounts of adipose or fatty ti sue surround the glandular tissue. • Size variation from individual to individual is due primarily to the amount of adipose or fatty tissue in the breast. • The amount of glandular tissue is fairly constant from one female to another. • Because lactation or the secretion of milk is the primary function of the mammary gland, the amount of glandular and fatty tissue, or the size of the female breast, has no bearing (behavior) on the functional ability of the gland. • The skin covering the breast is seen to be uniform in thickness, except in the area of the areola and nipple where the skin is somewhat thicker.
