MRI — The Amazing Imaging modality which transformed Medical Science, and, Nobel Prize

Few discoveries have truly transformed the modern medical science as much as imaging modalities , beginning from the discovery of “X – rays “in 1895  by Conrad Röntgen  ,  followed by computer processed combination of ‘ X – rays , the Computed Tomography Scan(C T Scan ) , which produced cross sectional images as virtual “slices “of body , allowing us to visualise the internal structures without cut – opening  it  ie non-  invasively , almost like imagining a fantasy !

CT Scan has been a remarkable discovery leading to the award of prestigious Nobel Prize in Physiology or Medicine, in the year 1979 to South Africa born American Physicist Dr Allan Cormack and British electrical engineer, Dr Godfrey Hounsefield .

MRI (Magnetic Resonance Imaging) went further and completely transformed the imaging process as this is extremely safe and equally versatile in acquiring images because it uses  safe – magnetic field gradients and radio waves instead of ionising radiation in CT scanner, to gather the pre requisite informations which is effectively converted into 2D and 3D images in any desired plane.

Unlike modern CT Scan, MRI remains quite costly because of heavy maintenance cost due to the necessity of keeping the superconducting magnet functioning in artificially created extreme cold environment effected by liquid Helium and a layer of liquid nitrogen around the magnet.

MRI takes a lot of time to complete the study and is prone to movement related artefacts easily.  These remain cause of worry.  Restless people and children find it difficult to take the test. Also for people who are claustrophobic (fear for narrow space) and dislike loud noises, produced by radio pulse generators or those who have metallic implants in their body, are not advised to take this test . Recently a lot of welcome changes have taken place in their design to address the above problems but it has only enhanced the cost substantially and has restricted its use in resource poor countries.




Red Sea Troop Base Attacked by Yeman

Western and UN experts say that Iran has provided weapons and support to the Houthis in Yemen during the country’s years of war. Iran denies the post-armed Hus, even though the parts found in the rebel weapons have links to Tehran.

Red Sea: The Red Sea (also the Erythraean Sea) is the sea inlet of the Indian Ocean which is located between Africa and Asia. The connection to the sea passes through the Bab el Mandeb Strait and the Gulf of Aden in the south. To the north are the Sinai Peninsula, the Gulf of Aqaba and the Gulf of Suez (towards the Suez Canal). The Red Sea Rift Valley is part of the Great Rift Valley, on the ocean floor. The salinity of the Red Sea is higher than the world average, about 4%.



MoU Between Department of Animal Husbandry and Ministry of AYUSH

The Ministry of Animal Husbandry under the Ministry of Fisheries, Livestock and Dairy and the Ministry of AYUSH signed a memorandum of understanding to introduce the concept of Ayurveda and its related disciplines into veterinary medicine. Help establish a regulatory mechanism to use Ayurveda in the field of veterinary medicine. Highlights:

It will also focus on capacity building in related fields through training.

The memorandum of understanding will explore the marketing possibilities of herbal medicines on a sustainable basis.

It will provide the cultivation, protection and preservation of medicinal plants.

The cooperation will develop a herbal veterinary education program.

It will make farmers and dairy farmers aware of the importance and utilization of herbal veterinarians and the cultivation of herbal medicines. Animal Husbandry in India: According to the “2021 Economic Survey”, the contribution rate of livestock increased from 24.32% in 2014-15 to 28.63% in 2018-19. According to the 20th Livestock Census, the total stock of livestock in India is 557.8 million. India has the largest livestock population in the globe.

PLI Scheme for Air Conditioners and LED Lights – White Goods

The Union Cabinet approved the production-linked incentive (PLI) plan for white goods (air conditioners and LED lights) with a budget of Rs. 62.38 billion. Highlights:


The PLI plan for goods manufactured in India will provide companies engaged in the manufacture of air conditioners and LED lights with incentives of 4% to 6% for the incremental sales of goods manufactured in India within five years.


Entities that enjoy benefits under other government PLI programs. India will not be eligible for this program. It will be implemented as a pan-India plan.


The plan may benefit many global and domestic companies, including many small and medium enterprises.


Lab on Wheels New Education Scheme in Delhi


Deputy CM Manish Sisodia unveiled the Wheel Technology Lab, which is part of the Delhi Technical University (DTU) “Education Reach You” program.  Highlights:


The laboratory will provide science education for students and disadvantaged children of Delhi government schools. The minister also unveiled DTU’s new classroom complex Pragya Bhawan and the new centre of the design department.


The wheeled laboratory is a vehicle equipped with 17 computers, two A customized bus with a computer. Televisions, a 3D printer, cameras and ordinary printers will be pulsating in the city to provide educational lectures, tutoring and teaching to students, which is part of its expansion plan to guide students in the development of mathematics, science and advanced technology.


Chaff Technology by DRDO



The DRDO has developed advanced Chaff Technology to protect the naval ships from enemy missile attacks. Highlights:


The Defense Laboratory Jodhpur (DLJ) of DRDO (Defense Research and Development Organization) Laboratories has indigenously developed three variants of the technology- Short Range Chaff Rocket (SRCR), Medium Range


Chaff Rocket (MRCR) and Long Range Chaff Rocket (LRCR) that meet the requirements of the Indian Navy.


Chaff is a passive, expendable electronic countermeasure technology used worldwide to protect naval ships from enemy radar and RF (radio frequency) missile seekers.


Launch of Integrated Health Information Platform – IHIP

The Integrated Health Information Platform (IHIP) was launched by the Ministry of Health.  Highlights:


IHIP is the next generation highly streamlined version of the Integrated Disease Surveillance Program (IDSP) currently in use.


Among the nations, India is the first country to adopt this advanced disease surveillance system.


It will accommodate the data entry and management of the Indian Disease Surveillance Program.


In addition to tracking the current 33 diseases (compared to the previous 18 diseases), it should also ensure that near real-time data is provided digitally.


It is also the world’s largest online disease monitoring platform.
