Advanced imaging solutions for accurate diagnosis

Radiography is a type of imaging that uses electromagnetic radiation to view the inside of the body, especially bones and certain tissues. It is a fast, painless, and non-invasive diagnostic tool. When computers are used to capture and display the images, it is called digital radiography.

Key Equipment at Sachdeva Diagnostics:

  • High Frequency 600mA X-ray Machine (Medtronics)
  • Top-end AGFA CR System for Digital X-rays

Safety Note:

  • X-rays involve ionizing radiation, but the dose is generally very low, especially in digital radiography.
  • Not recommended for pregnant women unless absolutely necessary. Baby is covered with a lead shield if done.

Common Types of X-rays:

  • Chest X-ray: Lungs, heart, chest wall
  • Abdominal X-ray: Bowel obstruction, stones, masses
  • Dental X-rays: Teeth, bone loss, cavities, roots
  • Bone X-rays: Fractures, dislocations, arthritis

Preparation: Most plain X-rays don’t require preparation except KUB (Kidney, Ureter, Bladder) where a laxative is advised one night before and the scan done on an empty stomach.

Special X-rays

Orthopantomogram (OPG): A panoramic dental X-ray for full jaw & teeth.

  • Captures entire mouth in one image
  • Non-invasive, quick, painless
  • Low radiation

Uses:

  • Tooth development, eruption patterns
  • Detect impacted teeth, jaw fractures, tumors
  • Planning orthodontics or implants
  • Check TMJ disorders

Contrast X-ray Studies:

  • IVP (Intravenous Pyelography) → urinary tract
  • Barium studies → GI tract (swallow, meal, follow-through, enema)
  • HSG (Hysterosalpingography) → uterus & tubes
  • Sonogram/Fistulogram

HSG: Done between day 7–10 of cycle, uses a cannula and contrast. At Sachdeva Diagnostics, performed by Dr. Savita Sachdeva (5,000+ procedures in 20 years).

IVP: Visualizes kidneys, ureters, bladder with contrast dye injection. Used for stones, tumors, UTIs, structural issues.

  • Requires fasting + laxative
  • Series of X-rays after contrast injection
  • Risks: rare allergy, not ideal for poor kidney function

Barium Studies: Uses barium sulfate for GI tract.

  • Barium Swallow → pharynx, esophagus
  • Barium Meal / Upper GI → stomach, duodenum
  • Barium Follow-through → small intestine
  • Barium Enema → colon, rectum

Preparation: fasting, laxatives (for lower GI).

Ultrasound Scan (Sonogram) is a non-invasive imaging test that uses high-frequency sound waves to create real-time images of structures inside the body.

How It Works:

  • A device called a transducer emits sound waves.
  • These waves bounce off tissues and organs.
  • The returning echoes are captured and converted into images on a monitor.

Key Features:

  • No radiation (unlike X-rays or CT scans)
  • Safe for pregnant women and babies
  • Provides real-time imaging (great for observing motion, like fetal heartbeat)

Equipment at Sachdeva Diagnostics:

We use the latest Samsung RS 85 Prestige Whole Body Ultrasound Scan System, fully equipped with an array of probes: Convex, High-frequency Linear, Intracavitary (TVS, TRUS), and 3D/4D.

Common Uses of Ultrasound:

  • Obstetric: Monitor pregnancy, fetal growth, heartbeat, position
  • Pelvic: Uterus, ovaries, fallopian tubes, bladder
  • Abdominal: Liver, kidneys, gallbladder, pancreas, spleen
  • KUB: Kidneys, bladder, prostate
  • Vascular/Color Doppler: Blood flow in arteries and veins
  • Musculoskeletal: Muscles, joints, tendons, soft tissues

Specialized Ultrasounds:

  • 3D/4D Ultrasound: Shows fetus/organs in three-dimensional view.
  • Transvaginal/Transrectal Ultrasound: Close-up internal imaging using special probes.
  • Color Doppler: Visualizes blood flow through vessels using color-coded imaging.
    Purpose: Assess direction, speed, and volume of blood; detect blockages/clots; check fetal blood flow; monitor organ perfusion.
    Common Uses: DVT, varicose veins, carotid artery, pregnancy circulation, transplant assessments, testicular torsion.
  • Shearwave Elastography (SWE): Measures tissue stiffness (especially liver, thyroid, prostate, breast, muscles, tumors).
    How It Works: Tracks shear wave speed → faster = stiffer tissue, slower = softer tissue. Produces a stiffness map (elastogram).
    Common Uses: Liver fibrosis (Fibroscan), breast & thyroid nodules, prostate evaluation, muscle/tendon strain, lymph nodes.
  • Fat Quantification (QUS): Evaluates liver fat using TAI (tissue attenuation index) + TSI (tissue scattering index) to give Fat Fraction % (UDFF).
    At Sachdeva Diagnostics, we provide both Fat Fraction % (UDFF) and TAI values — ensuring superior accuracy compared to centers providing only CAP/UGAP.
