MR angiography is a type of MRI scan that uses magnetic fields and radio waves to provide pictures of blood vessels without using a catheter. It has advantages over conventional angiography in that it is less invasive, less expensive, and faster. Disadvantages include not depicting small vessels or slow blood flow as well. There are various techniques used in MR angiography including contrast enhanced MRA, which uses gadolinium contrast to visualize vascular structures, and non-contrast MRA such as time-of-flight angiography and phase contrast angiography. Artifacts that can occur include metal artifacts from implanted devices and blooming artifacts around paramagnetic substances.Mri safety

Magnetic resonance angiography (MRA) uses magnetic resonance imaging (MRI) techniques to image blood vessels. There are three main types of MRA: time-of-flight angiography (TOF), phase contrast angiography (PCA), and contrast enhanced magnetic resonance angiography (CE-MRA). TOF uses gradient echo sequences to create bright vascular images from the signal difference between saturated and unsaturated spins moving through tissue. PCA images blood flow velocity using phase information and velocity encoding gradients. CE-MRA uses gadolinium contrast agents to shorten the T1 time of blood, allowing vessels to be visualized as their signal differs from the surrounding tissue.CT Head (Cerebral) Angiography.pptx, internal carotid artery. 2- vertebral a...

There are several key factors that affect MR image quality including signal to noise ratio (SNR), contrast to noise ratio (CNR), spatial resolution, and scan time. SNR depends on factors like proton density, voxel volume, TR, TE, flip angle, bandwidth, and coil type. SNR can be improved by using spin echo sequences, avoiding short TR and long TE, using the proper coil and tuning, and using a coarse matrix, large field of view, thick slices, and more signal averages. Increasing parameters like TR, slice thickness, field of view, and number of excitations can increase SNR but reduce other factors like spatial resolution or increase scan time.MRI Procedure of Brain

油
This detailed presentation by Dr. Prabhat Pandey (DNB Resident, Tata Main Hospital, Jamshedpur) provides a comprehensive overview of acetabular labral tears, covering their anatomical, biomechanical, and clinical implications. Beginning with the anatomy of the acetabular labruma fibrocartilaginous structure critical for hip joint stabilitythe presentation explains how its vascular and neural distribution contributes to both pain and poor healing potential when torn.
The pathophysiology of labral tears is discussed in the context of altered joint mechanics, loss of the labral seal, increased cartilage stress, and subsequent joint degeneration. The presentation classifies labral tears based on location, morphology, and etiology, highlighting causes such as trauma, femoroacetabular impingement (FAI), developmental dysplasia of the hip (DDH), and biomechanical imbalances.
Key clinical features are outlined, including chronic anterior hip or groin pain, mechanical symptoms like clicking and locking, and delayed diagnosisespecially in athletes and women. Diagnostic strategies include physical tests (e.g., FABER, McCarthy test, anterior impingement test), imaging (X-ray, CT, MRI, and MR arthrography), and diagnostic injections.
Management strategies range from conservative treatmentrest, anti-inflammatory drugs, and physiotherapyto surgical options, such as arthroscopic debridement and microfracture techniques. Postoperative rehabilitation focuses on early mobilization, DVT prophylaxis, and gradual return to function, tailored to reduce recurrence and promote joint preservation.
This presentation is an excellent educational resource for orthopedic residents, sports medicine practitioners, physiotherapists, and clinicians managing hip pathologies.Personalized Autism Therapies: Where Are We Currently?

Congenital Vertical Talus (CVT)also known as Congenital Convex Pes Valgus or Teratologic Dorsolateral Dislocation of the Talocalcaneonavicular Jointis a rare but significant pediatric foot deformity, characterized by a fixed dorsal dislocation of the talonavicular joint and rigid hindfoot equinus. This unique anatomical disruption gives rise to the hallmark "rocker-bottom" deformity, often evident at birth.
In this comprehensive presentation by Dr. Prabhat Pandey, DNB Orthopedics Resident at Tata Main Hospital, we explore every crucial aspect of Congenital Vertical Talusfrom its pathoanatomy and etiology to detailed clinical assessment and advanced management strategies. This 際際滷Share is tailored for orthopedic surgeons, pediatricians, medical students, and physiotherapists engaged in pediatric musculoskeletal care.

Revision Total Hip Replacement (THR) is among the most demanding procedures in orthopedic surgery. Unlike primary THR, it involves addressing pre-existing complications such as implant failure, dislocation, bone loss, or infection, often in the presence of compromised soft tissues and bone quality. While primary THR offers high success rates and reproducible outcomes, revision THR requires greater surgical expertise, meticulous planning, and personalized execution to restore function and minimize complications.
This presentation by Dr. Prabhat Pandey is designed as a comprehensive resource for orthopedic surgeons, residents, and joint reconstruction teams who seek to understand and master the essential principles, decision-making algorithms, and advanced techniques used in revision THR.
Revision hip arthroplasty is associated with:
Increased operative time and blood loss
Higher complication rates: infection, dislocation, thromboembolism, nerve injury, and periprosthetic fracture
The need to manage weakened bone stock and soft tissue envelope
Difficulty in removing failed implants, including intramedullary components.
Revision surgery is warranted in cases of:
Prosthetic dislocation or instability
Mechanical loosening of components
Implant wear or breakage
Periprosthetic fracture
Deep infection
Osteolysis or bone resorption
Painful loosening without overt signs of mechanical failure
Each case demands tailored intervention based on the severity and combination of these factors.
3. Principles of Successful Revision THR
Safe removal of loose or failed components
Preservation of host bone and soft tissue integrity
Effective reconstruction of bone defects using bone grafts or metal augments
Achieving stability of the revision components
Restoration of biomechanics, particularly the anatomical center of rotation.
Dislocation rates:
0.310% in primary THR
Up to 28% in revision THR
Influencing Factors:
Surgical approach
Abductor muscle function
Component malpositioning
Patient compliance
Prosthesis longevity
Underlying diagnosis (e.g., hip fracture, neuromuscular disorder
Revision Total Hip Replacement is not merely a technical endeavorit is a test of surgical judgment, experience, and adaptability. Successful outcomes hinge on:
Thorough preoperative assessment
Judicious use of classification systems like Paprosky
Proficiency in implant removal
Skillful reconstruction of defects
Meticulous postoperative care
This presentation distills the complex decision-making process into an organized, practical guide for any surgeon facing the challenge of revision THR.
