Angiography

 Angiography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers.


An arteriography is a procedure that produces an image of your arteries. During the procedure, your doctor will use contrast material, or dye, and X-rays to observe the flow of blood through your arteries and note any blockages. This procedure, also known as an angiogram, can be done on many different parts of your body.

Venography is a procedure to demonstrate the veins by using contrast media and others materials as for arteriography

INDICATIONS 

• Blockage of the blood Vessels.
• Suspected aneurysm.
• Renal artery stenosis.
• Renovascular hypertension.
• Trauma.
• Palpable renal masses.
•Chronic pyelonephritis.
• Renal abscesses.
and determination of the suitability of a (donor) kidney for renal transplantation.

CONTRAINDICATIONS 

  • Coagulopathy.
  • Decompensated congestive heart failure.
  • Hypertensive crisis.
  • Stroke or CVA.
  • Refractory arrhythmia.
  • GI hemorrhage.
  • Pregnancy.
  • Inability for patient cooperation.

EQUIPMENTS 

  • Angiography Systems.
  • Angiography Catheters.
  • Angiography Contrast Media.
  • Vascular Closure Devices (VCDs)
  • Angiography Balloons.
  • Angiography Guidewires.
  • Angiography Accessories.


PATIENT PREPARATION 

Don't eat or drink anything after midnight before your angiography,
Take all your medications to the hospital with you in their original bottles. ...
If you have diabetes, ask your doctor if you should take insulin or other oral 
The patient will change the cloth into hospital gown.

An angiogram uses X-rays and a special dye (contrast) to take Image of the arteries in your brain, heart, and kidneys. The dye is injected into a small tube or catheter into a vessels in your groin or (sometimes) your arm. The small tube is inserted after an injection of local anaesthetic around the vessels.

FOREARM X-RAY

The basic projections are A.P and Lateral ➢ Antero posterior (A.P):- The patient is seated along side of the table, with the affected side nearest to the tabletop. The arm is abducted and the elbow joint is fully extended with the forearm resting on the table. Centering point: - Center to the middle of the cassette or to the mid shaft of the bone. ➢ Lateral: - From the antero posterior position, the elbow is flexed and the humerus is internally rotated to bring the medial aspects of the upper arm, elbow, forearm, wrist and hand in contact with the cassette. Centering point: - Center to the middle of the cassette or to the mid shaft of the bone. Essential image characteristics . The image should demonstrate the radius and ulna, soft tissue outline and part of the wrist and elbow joint. References: MIT. Abdussalam A.

The Skull Anatomy

Learning Objectives For The Skull •  List and identify the bones of the brain case and face • Locate the major suture lines of the skull and name the bones associated with each. • Define sinuses and identify the location of each • Identify the bones and structures that form the nasal septum and nasal conchae, and locate of the hyoid bone •  Identifythe bony openings of the skull Anterior View of the Skull  Lateral View of Skull Bones of the Brain Case Parietal Bone Temporal Bone Frontal Bone Occipital Bone Sphenoid Bone Ethmoid Bone Sutures of the Skull Facial Bones of the Skull Maxillary Bone Palatine Bone Zygomatic Bone Nasal Bone Lacrimal Bone Inferior Nasal Conchae Vomer Bone Mandible Paranasal Sinuses Hyoid Bone The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclo...

HAND X-RAY

The basic projections are P.A and Lateral , ➢ Postero anterior (Dorsi-palmar P.A):- The patient is seated along side the table, the forearm is placed pronated on the table with the palmar surface of the hand in contact with the cassette. With the fingers slightly separated and extended to ensure that they remain in contact to the cassette. Centering point: - Center to the head of the third metacarpopalangeal joint. ➢ Dorsi-palmar oblique: - From the PA position the patient will now rotate his/her hand approximately 45° degrees, ➢ Another modified 15° degrees, Centering point: - Center to the 4th metacarpal bone. Essential image characteristics, The image should demonstrate the bones clearly and soft tissue outline no rotation or motion. References: MIT. Abdussalam A. Madaki and Cowen A.R (2019) Tutorial on the image quality characteristics of radiographic screen film combinations and their measurement, (medical Devices Directorate Evaluation report), MDD/94/34,ALTH.
